TESTs
IMPACT GUNS SPEEDS
4200rpm with I/M style and Automotive Style fittings
5700rpm with V-Style fittings
DIE GRINDER SPEEDS
3000-5000rpm increase with V-style(tested by ear as the speeds exceed my meters capacity)
SIZE FLOW
.031sq inches to flow air with I/M and Automive fittings
.040sq inches to flow air with hand DRILLED out I/M fittings
.071sq inches to flow air with V-Style fittings
Thoughts:
I feel like the tools are around all around 50% more powerful. Milton claim 70% more air flow and the math/dimensions seam to add up. I did tear down the couplers and they have far larger holes than a standard coupler as well. I opted not to buy the Harbor Freight Merlin High Flow, because upon closer inspection they seem very crappy(technical term) and in this case they were more ($10 for 4pcs) than the top of the line Milton($20 for 14pcs).
I have drilled out M fittings in the past but didn't feel any improvement as you can only go a tiny bit. I have also done the same inside the M coupler but you can't do much in those without compromising the integrity. The standard M fittings has a hole with the surface area of .031sqaure inches; where the V style are .071 square inches. Drilling may get you up to .040 but the V style still flows twice the air.

This video is NOT a paid endorsement. I have never communicated with Milton nor did I receive these for free. I bought them directly from Amazon.
I did some tests today.

Won't make much of a difference for air blow guns
I've been using the same fittings on all my air tools and have experienced similar results. You can actually hear and feel a vast difference.

Makes a HUGE difference when painting with a high end HVLP Spray gun, glad I purchased these, for the price, really good value.
I appreciate you saving everyone's ears by turning down the volume during the impact gun use! 👍
Thanks, I'm glad you liked it.
The problem is when I bought the red ones before I saw the purple ones
I used th-cam.com/users/postUgkx4ynqaujg7rZKFapA8s29kTpRszJGa3-K this for the first time today to replace the front wheel bearing on my rwd 98 dodge dakota. This had absolutely no issue removing or reinstalling the lug nuts and it took off the axle nut without any struggle. Sounds like it's got some muscle to it. Time will tell
Gotta love it, man and his best friend. He was so dissapointed in himself for letting you down. That is great. I'm gonna get me a set of those high flow miltons. Thanks man for sharing.
It's impressive the difference it made.
When I first got my "800 ft. lbs" impact, I tried it with 1/4 coiled air
hose and it would not remove any lug-nut. I thought it was defective.
Changed to a 3/8 hose and now the same impact has removed every lug-nut
I've tried. I look forward to trying the Milton's Hi Flows.
When I first set up my shop I had those 1/4" coils. They're handy but really kill the air flow.
@@sixtyfiveford
I won't ruin it for everyone else , but years ago I got the husky ones at the depot.
I could tell right away because the ol ir2131 barely needed a brap on the lugnuts.
Dual stage at a shop it was awesome , but after I left there I kept it at my (play) shop.
I was bummed about it's performance on a single stage compressor , but the high flow fittings made me feel about 70% better 😆
What I mean is the fittings gave me back what I felt was close to 70% of the performance of running it on a dual stage.
I'm running half inch hose with the milton high flow fittings and it is a huge gap between the 3/8s hose with their fittings to the half inch hose with their fittings
I've been using Milton Hi Flo for over a year now and they are amazing.
I can't believe it took me so long to buy them.
@@sixtyfiveford I made an adapter with a regular connector on one end for the occasion that I use a tool that doesn't have a hi flo end. Although I converted all mine you never know maybe someone loans you a tool without a hi flo.
WOW you're workshop is looking great! And as always you put out a great video. You remain one of the best content putter outers! 😆 🤣
@@sixtyfiveford what's the difference between the M, V, etc?
these fittings are 100% the way to go. Never going back!
High flow V-style for life. Tremendously better in every way compared to the standard ones. easier to use as well.
My air compressor is fully upgraded with high flow everything and larger 3/8 hose. only a 6 gallon 4.2cfm but still can run anything I throw at it. the bigger stuff can work well in short bursts still too. impact wrenches work well when used in short bursts. doesnt suck too much air.
Good to know as I only have 6 gallon Makita for homeowner type garage and woodworking pneumatic nail punch on hardwood pallets. He made me feel as if I’d need a 60/80 gallon tank. Thank you for sharing.
LOL, I love the dog scene at the end. The dog puts on such a show of remorse and tries get your sympathy. Hilarious.
When I was visiting a friend's street rod shop (shout out to Big Oak Garage) I noticed that even with air hoses everywhere there were no audible leaks. I asked and he said he used Milton. My Chinese connectors leak all the time even when new. Just got a new compressor and went with the Milton brass V couplers and steel plugs. If I gain some performance that's a bonus. Although I have a generous collection of air tools I mostly blow away chips/sawdust and drive small brads/nails. The main reason I went with the V system is the ease of connecting and disconnecting.
10/4 on the Miltons and you can HEAR the difference between the regular and Hi-flow. LOTS more power on the hi-flow! Good job!
Such a difference.
@@sixtyfiveford TRUE! I sure like those compressors especially the bigger one. That is a COMPRESSOR!
Went over to 3/8 hoses and Milton Hi-flo "V" style a year ago. Never looked back. The plugs are cheap enough when you buy a pack of 20, to change everything over, the sockets are a bit more expensive but, in my opinion, worth every penny.
Glad you are making money but one reason I liked your videos so much was your relatable junky messy shop. Keep up the great work 💪
I have that same IR 3/4" gun, it's power ratings are with 1/2" air line at 95 psi.
So no doubt would greatly benefit from more air flow over the 1/4" fittings.
I got a set in my Amazon cart!
Thanks
I ran it with a large hose when I got it. It just isn't fun dragging that 1/2" hose around.
Not sold on the test methodolgy, but the difference in sound alone is clear. P.S., if you like air tools, buy the harbor frieght extended 4" cutoff tool. Best air I've ever used.
Awww your pup at the end was adorable, I felt so bad for him/her! Wanted to give him/her a big hug AND another sandwich hahaha. Great video, thanks for the indepth info and comparison!
She got some fries for her great show.
I purchases the same kit from The Home Depot app back in March for $20.82. I bought them along with a brand new air compressor and F.R.L. Upon receiving the couplers, the absolute first thing I noticed was the huge holes! This was the first time seeing them and I do have to say that the airflow is great! Maybe not the full 70% that Milton claims but it's pretty close. I can most definitely tell the difference like you did when you go and use an older coupler. This "V style" purple colored high flow set is the way to go. You won't be disappointed. Many of us have purchased and love em!!!
Miltons are the only brand I've used that don't leak or have excess play. Your filter on your compressor will catch some dirt and oil but will need to be downstream at least 50 ft to catch water. The air exiting the xompressor needs time to cool down which then condensate so the filter will not catch water. This doesn't matter too much if you're not painting but if you want really clean air running through your all your tools then you should relocate the filter and maybe think about a 3 stage. Thanks for the heads up on the v style. Your vids are always super informative!
For the most part here in Utah we have such low humidity it's not a major concern. But painting definitely needs a better dryer system than the tiny one I have.
Thanks for great vid! I noticed your old "M" style plug seemed to work in the new "V" style socket. Conversely I have had instances where the "V" style plug will not even go into an "M" style socket. If you look carefully and measure, there IS a difference in the "V" and the "M" styles. I saw a vid by some guy that showed a dangerous situation with fittings blowing apart because these 2 slyles don't fit perfectly. Just eyeball them side by side. You can see the difference! Be careful mixing "V" and "M"!
I just ran into this today, high flow doesn't fit normal flow
The Pup was the best part, the hell with the fiitings..
Thanks for making this video I work for an abrasive and tool company. As you showed with the cut off tool, these high flow fittings are excellent on cut off tools and 4.5” grinders. They will even make a big difference on your little roloc die grinder too!
The high flow fittings is all we use in our paint booths at work. There is a huge difference when we use an adapter in order to spray a small piece out in the shop floor...
But you are right that it wont benefit all air tools.
Good vid!
I've always wondered if they were better, I now know. Great vid.
It's a noticeable improvement.
I just switched over to the HF branded high flow fittings and I absolutely love them and swear by them. The increased flow is very noticeable. Thanks for posting this my Friend! Cheers Moe! Zip~
Oh no. First I'll change out the V fittings, then the compressor won't keep up, so I'll need an extra tank or maybe another compressor. Little projects like this have a way of escalating. I like the 1/4" style, so at least you can change out only those devices that need the extra flow. Going to 3/8 will likely work better but would need a broader switch. On the other hand, maybe one could use 3/8 for proximal line, then swap out a distal line with 1/4 V style fittings....
Question for you so I just got new little 175psi compressor but the hose leaks at the end where fitting is tired airing up tire wouldn’t even put 10 psi in tire The tank fills up fine I can feel the air in the hose ain’t got a clue is wrong with it do you?
v style are a high maintenance option. The couplers constantly cook off and continuously blast air out until you replace them. They are also a royal pain to connect especially when you use them a bit. I used them for 3 years in my shop and finally had enough to switched to "P" Style fittings and couplers thru out the entire shop and they flow more than the v style and have never had one leak or wear out in over a year now.
We run 160gallons of air at 180 psi unregulated for what its worth.
Performance never goes out of style...Great video.
Well Said.
The V style fittings have been since the 90s, I believe. That's how log I've been using them anyhow. My local farm store had run out of M type and a guy I knew said these were the same but with a larger passage. There was no marketing for them, then. Actually, I saw them at the same farm store with normal Milton packaging last week.
The Mac Tools guy even told me thats what is used to spec their impact wrenches.
I had no idea these existed since the 90's
Good to know...
Great info, thanks! Looks like I will be switching over . You always have such awesome ends to your videos, but this one tops the cake! Stay well!
Thanks, I'm glad you liked it.
I can tell you from years of working on class 8 trucks hi flow fittings make a big difference.Also that 3/4 impact should have a 1.0 inch hose and a bigger qd.fitting
I did have 1" hose a few years ago. What a pain to drag that around, but dang the gun had power. The hose ended up getting shelved as I mainly only use it for cars so it takes everything off even with the restriction. From time to time I need to pull out the big hose and fittings though.
@@sixtyfiveford Yep for cars and pick ups 1/2 will do. ....and a torch!
I can commiserate with Ginger.
I would have ate that chicken sandwich too.
would have EATEN that sandwich ...
@@ericleger8158 You have fulfilled the purpose of your life.
You have no reason to continue to live.
Although you never really had one either.
Chicken sandwich? Nope no chicken sandwich to see here. LOL
#metoo
@@ericleger8158 I would of went or gone, ate that chicken sandwich myself too.
I too use the Milton Hi-Flow fittings and I can hear and see a performance difference on my air tools.
I had to laugh that your dog did not eat the pickle, but everything else was completely gone. Pretty funny
Hey Thanks. I have upgraded all but a few non crucial things to the Milton Hi-Flow.
I think I might need some of these connectors. Good test and quite convincing, especially on the cutoff wheel. Thanks Moe
My cheap cutoff die grinder has never spun so fast.
Thank you for the video. good comparisons and glad you listed everything you used in the test.
Glad it was helpful! These are awesome.
I was going to comment about the subject at hand but as soon as I saw that "I'm sorry I ate the sandwich" face I forget what just happened.
She tried so hard. After 5 minutes she hadn't touched it but 10 minutes was just too long to wait.
i used calcium chloride pellets for moisture removal and after 10 years it rottec all of my air tools and all of my lines in a 400 sq foot home shop...I now use tags in a flanged pressure container and it works perfectly...I replaced the tools, switched ($3000) over to plastic lines and high flow fitting, all so that I could do pinion nuts and other high torque fasteners...God bless...doug
I've never heard of Calcium Chloride being used as a desiccant. Luckily we have such low humidity hear it's never a big issue.
@@sixtyfivefordthey use calcium choride on the grid toads in front of peoples yards when the dust gets bad up here it holds the moisture until it gets very hot(rots the body metal as fast as all the salt they use, dadgummit)... I meant to say I used rags , a friend uses an old pair of coveralls and he paints a lot with no probs...I m actually using a stack of paint booth air filters now ...sure enjoy your vids...prepare for the worst and expect the best friend...doug (kanada)
Not alot of people know it but you can install the V style couplers on you're compressor and hoses and still use the M style fittings in them if you don't have all you're tools changed over yet
They work best for high flow applications like sand blasters, and you can really see the difference if you use it for painting cars.
I was also under the impression these were mainly for use with HVLP spray guns. Nice to see they have a little benefit to other tools, as well.
I’ve seen people drill out the tool port itself to gain more power but this is such a simple solution. Although I’ve been getting away from air going to cordless, I still run a 60 gallon with a 21 reserve tank in line so for twenty bux to change over my shop, it’s done deal! Thanks for the heads up! Ginger should get a second chicken sangy based on that cuteness overload alone! 😍✌🏼
I have drilled them out in the past but didn't feel any improvement as you can only go a tiny bit. I have also done the same inside the coupler but you can't do much in those without compromising the integrity. The standard M fittings has a hole with the surface area of .031sqaure inches; where the V style are .071 square inches. Drilling may get you up to .040 but the V style still flows twice the air.
I actually sold off my small 3/8 Snap ON and 1/2 Mid Size impact a few months ago as I replaced them with cordless. My biggest complaint with cordless is they do not feel as solid and vibrate, rattle all over the place to do the same job an air impact does with nice solid hits. Air is like riding in a Cadillac, the cordless is like riding in a covered wagon down a dirt road. Both do the same job, one just beats you up more. I'm keeping the 3/4 Ingersoll and won't replace it with cordless.
sixtyfiveford: I don’t blame you one bit. That 3/4 is a beast and I love that 80 gallon endless supply tank you have too! I had an opportunity to get one of those for free a few years ago while I was hauling steel to a work shop they were renovating, but there was no way I could get that sucker off the trailer if they would’ve put it on with a forklift like they wanted to, oh well my loss. I kinda made up for it grabbing this 60gal Craftsman for pennies cause the owner said “it just stopped working” lol. A new ring kit and it’s building pressure like a champ so an $800 compressor for $40 works for me! Besides, I’m mainly keeping air these days for filling tires and blowing dust dirt and grime off of stuff but also for the wood shop for my brad, finish and framing nailer‘s because who the heck can afford to drop $400 for a new cordless nailer?! (I do have a pasload cordless 6v gas framer that I really like.) The newest dewalt and metabo/hitachi cordless nailers are really sweet too, meh, maybe someday... For now I have to do a complete accountability on all of my air tools so I can get a good count on what I need for connectors to include all the splice points and shut off’s everywhere in the shops and for the outside ports too. Last count was up to $60, but that’s still pretty cheap to ensure all that extra ooomph lol. Enjoy your day brother.✌🏼
I changed all my fittings over to high flow fittings going on 2 yrs ago , they are great specially on older tools , the only draw back is they at that time they didnt make a pressure relief coupler ,the high flow males dont work well with push button releases .i miss pushing the button and waiting just a second for the die grinder to pop off with no pressure behind it or the 50' air hose just falling off without bleeding the pressure off..
Loved the video! Great dog! and truck!!
It looks like these fittings are just far to soft. Lots of failures when used on impact tools, such as hammers, scalers, impact wrenches, etc.
Its the same issue as using brass, and Milton knows this!!! These fittings should be made of steel.
For a hobbyist that only uses a impact 1-2 times per month this might be sufficient. But if your in a shop setting, just get the 3/8 steel fittings.
They make these exact style fittings in brass and steel as well. I put a steel on my impact hammer.
I don't know I feel like the easiest way to test this would be to tighten them with the height flow fittings and see if the low flow fittings can loosen them and if not then that means the high flow fitting makes the impact more powerful
these seem to be great...and i like how you can still use standard 1/4 fittings with them also...
That's been one of the greatest features. When ordering this I forgot how many odds and ends(tire chucks etc) I had that have the smaller fittings. They really don't need high flow and have no issue working with the Milton V style.
Would have been interesting to see a comparison of the tool hard lined onto the hose too. My buddy has a shop with a few hose reels with tools permanently installed on them.
I just want ones that don't leak, I think I have a mish mash of connectors. Your Shop looks so clean and cool.
Thanks, I've been trying to clean up the shop. Leaking couplers drive me nuts. Miltons are the only ones that seam to last.
I'm using the type of quick couplers that have a button on the side to release them, Then the ones on the wall I use the regular old style ones.
I almost bought the Prevost style couplers a few times. The push button is very handy.
Good video and info. No dog is going to hold back from chicken when the coast is clear.
Oh, the guilt on his face! I love it! 💖😁. And by the way, good video!
The guilt was hilarious. Poor Ginger.
Hi. Do you think Flexzilla rubber hybrid air hose is a better hose than your Goodyear rubber in this video? Also, I see some WYNNsky amd JACO high flow air fittings on Amazon. Any good? Comparable quality to Milton, or stay away? Thank you very much.
I just use what ever fitting matches the internal diameter of the hose it’s connected to. My 10mm internal hose has the 10mm internal “euro” style fittings and my bigger 13mm internal hose uses the bigger 3 hole fitting. Once the fittings internal size is at least the size of the hose that’s as good as it gets, bigger than the hose and the hose is still the biggest restricter.
Hose size is very important.
That's what she said... Lol!
Keep in mind the restriction is in the coupling where the air has to go through turns and passages. I've seen at least 2 completely different V-style couplers (Milton and ???). I know all the paint shops moved from the V to a $28 coupler system (I think Provost is one) - I don't know anything about these $$$ coupler/plug systems.
Are these fittings required at all points along the line or just at the end of the line? Would love to hear your input. Thanks!
You need to start a new channel...call it Mo'Ginger...all about the pup!
Try torquing the nuts with the high flow fittings, and see if you can can get them off with the regular fittings. My thought is that more air flow allows it to hit harder, therefore tighter. Lower flow shouldn’t be able to break it free.
The only problem with that logic is that the break away reverse torque hits differently than the forward torque. It would not work, trust me. For example on a 2235TiMax, forward torque is 870 ft. lbs, but reverse busting torque is 1760 ft. lbs. He even said the same thing in the video 9:00.
Nice to know my instincts are still good. Also, you brought back bittersweet memories at the end there :o)
It's a ton of work training/owning a dog, but rewarding.
I bought 2 of those purple kits that you bought. I love them.
Back in the late 70s, A, L, & T were all that were available around here. Ts cost 3 times what the other 2 did, so I went with A. We never saw Ms until Campbell Hasenpfeffer started pushing their crap cheap, so I've always had a bias against M style, too bad, I'll bet that kit isn't $20 up here...
I had always wondered since You lead hose from the compressor, air hose itself the opening is standard. Should the inlets and outlets be drilled out to match the high flow fitting diameter to get the most out of it?
Lol! She just couldn't stand it, but give her credit, she did wait until you left...
Great video and testing Moe, thank you!
I like the better flow rate, but the thinner walls of the fittings worries me. I had a fitting break on me while under a car once and the hose end smacked me in the head, leaving a goose egg for a day or three. I'd be even more concerned about that happening again with thinner walled fittings. I think I'll stick with the old heavier walled fittings and just use my 3/8" hose hooked up direct with no couplings when I need the flow.
Yours truly, Knothead...
P.S. However, thinking about it some more, I bet they are made of better metal these days and you can't beat the price.
That doesn't sound fun. These purple ones are aluminum and though I don't think they would break they will likely ding/nick pretty easily. They do sell the same style in steel for higher strength.
Love your videos you're fantastic to learn from but I got-a tell ya your Dog is awesome! Very Smart it's funny to see how your dog reacts to you when your talking to it. We have a smaller dog that's a blue heeler terrier mix and she is just like that when you talk to her. Very funny love all the short videos at the end. Thank you so much for producing all these helpful videos I have learned so much from your channel. I subscribed to your channel and will plan on buying some of the things you have suggested through AMZ and will use your links to help you out. Keep up all the great videos!
Hey Thanks, I'm glad you like the videos and Ginger. Blue Heeler Terrier, that's awesome.
I ordered some of those they should be here today my impact gun will not remove lug nuts off of my truck hoping this will help
I just picked up a compressor recently and didn't know what fittings and what size to go with it being a ridgid tristack 5 gallon I think but could be wrong on that wanna go with 3/8 but whats on there i don't know if the couplers leak so I may go ahead and replace them with brand new ones im gonna have to see what size it has on it
At least he left you the pickle.
Great video as always
Nothing like a seat pickle.
Alright, my question is do the hi flow fittings hold up as well as the OG fittings, I know the cheap aluminum hi flow fittings that come on an impact from the tool truck that come in all the fun colors brake in a week of use swap it to a Milton and you’re good for a decent amount of time.
If i get the hi flow fittings on the coupler can i mix and match? Or do i have to have high flow with high flow? Also do they just press in easy or do i have to press the collar down on the coupler to get it to fit?
So when using my 1200 ft lb impact gun I have to have high flow all the way from the tank to every fitting all the way to the tool.. I have a 3-way manifold connected to a regular low-flow connector at the tank and 350 ft sections of hose in the manifold everything is low-flow connector.. if I want to use one of the hoses strictly for my impact gun can I just put a high-flow male on one end and a high-flow quick connect on the other end and a high-flow mail in my impact gun? Or will the manifold and the low-flow Quick Connect that the manifold is plugged into at the tank reduce my air flow? I only use my gun when I rotate my tires or do my brakes I am no kind of mechanic.. no I do use my die grinder to sharpen my riding tractor blades
The Ting is you have still a big hose and the good fittings on your tank... inmagin the difference with all standart parts...
I live in germany and have the standart NW 7,2... (7,2mm inside ) i dont know if it is compatibile but i reely would like to use them.
Now i only have a big hose (12mm/ 1/2 inch inner diameter) connected to the 1/2 inch port to my compressor... and only that make a difference over 1 Bar at the end of the hose vs the 6mm hose.
Thanks for the info and Heelers just can't help themselves.
When most of the comments are about the dog at the end. This friggin year man.
Thanks, I'm glad you liked it.
Bought some by mistake. Guess I'll give them a try.
Ginger couldn't resist. I don't blame her. 🤣🤣🤣
She tried so hard. I came out after 5 minutes and she hadn't touched it so I went back away. 10minutes was just too much time alone with the chicken sandwich.
Wonder if it would make a difference if compressor is only rated at 5 cfm
I think with the impact you would notice a difference with the small fittings if they couldn’t bust a nut loose you could with the high flow fittings. I couldn’t get the 33 mm lug nuts off my freight liner with my half inch impact gun but I have a long hose with tiny fittings. Came right off with a nut buster tool
You're playing with big lug nuts.
I can tell by the sound which one is slower but it's not enough to swap them out.
My fittings dont pop off when I pull back the coupler. I want it to be like the cool duds, how is that done?
I'm going to make up a gauge I can put at the end of my line and watch presure drop.
Do I need to change the female coupler that came installed on the tank from the manufacture?
I live in Sweden and can't get these without $30 shipping.
I'd pay $100 in shipping, trust me. Sanders and cutters are just different tools with these on and I'm pretty sure I could use my Mirka sander as a planer with 60 grit and some aluminium rails.
Im with the dog, i woulda ate it as soon as you were out of my sight too!! LOL Pup looked so disgusted with herself, lol
How are the high flow holding out.? Being Aluminum body.
They come in brass and steel as well. The one in my air hammer is beat up as it takes so much vibration but the others are all good. I haven't had to replace any yet, but I did buy a 3 pack of brass for $4 to swap the air hammer.
How have the aluminum plugs been holding up. I have read where some people have had problems with the aluminum plugs popping loose on their own. I have the high flow V-style myself but have the brass version.
The couplers have been holding up excellent with no leaking or wear whatsoever. A few of the air tools to have extreme vibration I noticed the fittings do have some wear. Like my air hammer for example the steel balls of the coupler start digging in to the retaining ring on the male fitting. I haven't had to change it out since I put it on but if I used the air hammer on a daily / weekly basis I would probably only get a few months. Things like my air check that I use on a daily basis show virtually no wear along with my die grinder etc all look great. The impact gun does show a little bit of wear and would likely only last a few months in a heavy shop environment. I definitely think brass is the way to go but I'm really impressed how will the aluminum ones are holding up.
Hey Moe, I just recently bought that same set from Amazon. The female coupler didn't last for me. They're aluminum right? I think some of my tools have steel fittings that work with the V couplers but wear the couplers out more quickly. I also found that the coupler isn't rebuildable.....well I couldn't get it apart anyway to try to repair it.
They do sell all steel versions of this that would outlast these aluminum. I prefer brass and I'm sure they sell that as well. I took the couplers apart the first day I got them. They were tightly fastened but a 6 point socket on top and a wrench got them apart. These use a simple round oring for sealing to the male half of the coupler. Should be much easier to rebuild these with of the shelf orings vs the special flat washers in typical Milton M couplers.
I have a 20 gallon tank and cannot remove my 150 lb torque lug nut on f150. I might try buying the high velocity coupling but cannot imagine it working. But u never know.
That's pretty cool they offer these. I actually use all Milton M style as well and I just put the male ends in the dril press and open them up a bit. Is the female side a larger diameter as well?
Yes, the Female couple is completely redesigned inside and has tons more flow than a standard coupler. I have drilled them out in the past but didn't feel any improvement as you can only go a tiny bit. I have also done the same inside the coupler but you can't do much in those without compromising the integrity. The standard M fittings has a hole with the surface area of .031sqaure inches; where the V style are .071 square inches. Drilling may get you up to .040 but the V style still flows twice the air.
Ya we had an air hose that i gues was collapsed or had some restriction in the hose you could tell the inpact hit hard at first then it calms down in a few seconds so make sure everything else is right is all im saying
Oh great something else to spend money on lol but looks well worth it and for $20 why not. Love the fact it can take an M style too
I didn't think I would feel such a noticeable power increase.
The problem is the 3/8 hose has a 1/4 ID barb... so whatever the airflow fitting or not, the 1/4 barb is the limit. So it's pretty obvious that even if the coupler after the barb is 70% bigger, it doesn't mean anything.
IMO those airflow fittings are most worth it with a 1/2 air line for higher airflow tools. So I'll keep a 1/2 line for high airflow tools and my other 3/8 lines for regular flow. Can all use those V fittings though why not, but I also kept a 3/8 hose with the regular M style coupler just because I have some random low airflow tools that are on it and I,m not changing the coupler of all tools to high airflow for no reason. But I changed the inlet to the V fitting so I can connect to my main compressor hose. Also need to keep a regular hose.
So imo those airflow fittings have a purpose only on a 1/2 line with high airflow tools.
You have your measurements all wrong. A 1/4" npt fitting has an internal size of approx 5/16". A standard I/M fitting has an outlet size of around 3/16". So you choke down a 3/8" hose to 3/16". A "V" high flow fitting has an outlet size of 5/16" The same as inlet. So you only choke down a 3/8 hose to 5/16. Which is .071" vs .030 (standard), so more than double the airflow area.
How do those compare against Flexzilla high flow fittings?
They're close but still not as good. They have a smaller hole opening
.031sq inches to flow air with I/M and Automotive fittings
.071sq inches to flow air with Milton V-Style fittings
.069sq inches to flow air with Flexzilla.
That's only the male fitting. The coupler is a whole different story. Most of the Chinese knock offs have a plug that covers the inlet when a fitting is plugged in. So they are worse than a regular IM fitting. I bought a few other brands after the video to just see and they all are worse(Amazon Basics, Harbor Freight Hi Flow, and two others). Just go with Milton and you won't be disappointed.
I saw these at my local norby's I'm glad you did a review on these I was wondering the same thing if they worked better it looks like they do. thank you
Thanks, I'm glad you liked it. I did speed tests today and the impact gun spins 1500rpm faster. The cutoff die grinder exceeded my rpm meter so I couldn't get exact but I would say it is spinning 3-5000rpm faster.
So can you put high flow coupler directly on your compressor? Can they be metal or do they have to be brass?
I have high flo on my compressor
If the restriction is at the tank end, the effect of the friction in the air flow through the length of the hose should have a greater effect on the tool end, even with the high flow fitting on the tool end.
True.
Thanks for this...wow, yeah a noticeable speed and sound difference. Ok, but why not go right to a H style with the 3/8" body and 1/4" npt threads? Wouldn't that flow even better because not only is the opening larger, but the body as well. Anyway, that is what I am leaning towards doing. WYNNsky has a nice 9 piece kit for under 20 bucks. You could still use your low flow tools with M style couplers with this setup by adding a H plug to a M coupler in front of the line coupler. What do you think?
Milton says 74cfm max for V-Style and 67cfm max for H-Style. Compare that to IM at 40cfm or T at 40cfm as well. I bought some off brand V-Style from Amazon and they had a way smaller drilled hole in the fittings and the coupler was probably 1/2 the internal size holes as the genuine Milton.
F' yeah she ate it
I woulda ate it!
Good doggo,, lol
I woulda done the same damn thing :)
Thanx for the heads up on the fittings
milton needs to put u on the payroll because if i ever buy them its gonna be because of this video.
I know right. They make great fittings.
Ok great video but I have some questions I'm hoping someone can help with. Apologies for my ignorance but these are the 1/4 plugs how are you using 3/8 hose?
I have a mac5200 with a 1/4 quick connect body and 3/8 body coming out of the compressor. So I figured I would use the 3/8 primarily.
I figured I would need 3/8 to 3/8 connectors with 3/8 hose but this is proving harder to figure out and find since everything seems to be 3/8 to 1/4 not. 3/8 hose on 1/4 connector is hurting my head 😂
Is the ID of 3/8 hose 1/4 or am I misunderstanding everything?
3/8" hose is the inside diameter. 1/4" npt fitting is the thread size and has an actual external size of around 1/2" and an approx ID of 1/4".
@@sixtyfiveford thanks, I thought using 3/8 hose with 1/4 plugs seemed odd. I guess it doesn't introduce any bottleneck?
Ive been using these foe a while now and my only complaint is the the purple aluminum fittings wear a little fast so I recommend spending a little extra to get the steel ones however I never could find them in a pack of ten like the aluminum ones.
Yeah, that was a concern of mine. I generally like brass or steel and will likely upgrade the ones that get more use.
@@sixtyfiveford ya i agree. I figured that I would just buy a few steel fittings for the tools that get the most use. I just wish they would sell the steel fittings in packs of 10 or so. They might but I didn't see them anywhere when I was buying all this stuff a while back.
@@sixtyfiveford
Yea I'm kinda partial to steel.
It's normal around a shop to throw the hose on the floor after unchucking a tool , and the brass ones deform after a while and the pullback thingee part
(technical as f**k)
gets jammed.
Steel lasts me a little longer.
Question for you on potential durability. I just order the 14 piece set to swap out all my tools and a hungry plasma cutter. I don't count myself as being abusive to my tools, though some get used to their full potential. I bought the set even after reading mixed reviews that this purple set is fairly soft but my connectors and such won't be in an auto shop setting where more abuse would be expected. Any thoughts now that you've had them a few years? (Hopefully they're still around!)
They've been holding up great. However I had one get damaged pretty quickly. It was on my air hammer so I bought a brass one for just that one. I think a 2 pack of brass male fittings was under $5. However even though it shows wear, I haven't changed it out because it doesn't leak. I use my blow gun nearly daily and it shows little to no wear. Now if I used the super high vibration air hammer on a daily basis I would need brass or even steel V style. None of the female couplers leak at all even when using the standard IM fittings in them.
Been using the high flow fittings for such a long time that I can't remember what the normal fittings are like. Maybe I need to go back for a little bit to experience some disappointment that'll make the hi-flows seem even better
8:00, the spin time is small percentage of the overall work time. So a small increase in efficiency will show as even smaller. The sound and apparent rpm was noticeably less using the standared coupler.
The feel in your hand while using the tool shows an impressive difference.
I started with the industrial fittings but switched to automotive for several reasons, I could barrow my dad’s stuff, others on the construction site could not use my compressor and I’ve found that the automotive aren’t as leak prone. I have used ingersoll ,cp, and the ones snap on sold but have not noticed and better quality than I get at harbor freight. I am now in a shop running what I think is the same compressor you have a Curtis e57. I may try these next time I have to buy fittings though I’m really wanting to try it on my ingersoll impact. But since you seem to have more pneumatic knowledge than me I have a question, who makes a good hose, I run 190psi and keep blowing hoses marked at 600psi. I’ve blown everything from cheap Chinese to ch craftsman Goodyear. What do you think?
I know that this comment is about 2 years old but for those asking the same question, I recommend the BLUBIRD 1/2 in. x 50 ft. Air Hose. I use it mostly for a Sunex SXMC12, 1/2" Mini Air Impact Wrench along wit other miscellaneous pneumatic tools. Rugged and gets the job done. Rated at I think 300 PSI...
More important than the size of your tank is how many stages does the compressor have.
