Thought for sure I'd be soldering copper, cleaning flux drip off the floor, having to deal with out of square walls on my bends... and now I see someone competent using Pex for air lines!! I'm saved!! Thank you :)
yes as one who sells and installs pex, it will work on air even compressor that put out 175psi, and I am sure were he is it is a warm climate, but here in the north were our winter are -40 most of the time, and it will be fine if your shop is heated, but if it is not heated, pex turns to like glass when it is -20, I used pex in my in heated shop, and when I use it I make a fire, I don't use the pex system in the winter, as pex turns to glass when it is really cold, leave a peace of pex out side at -20 and bend it, and see what happens, my pex system blow open a few times in the winter in the cold, the MFG SAYS NO, BUT USE IT if your in a warm place of heated
We use pex water line outside and inside house everyday never thought it hold that kind pressure till look on youtube channels. I got black pipe installed on my shop. Will not hesitate too expand my airline system with pex . Big plus with pex if use it outside and get water buildup in the lines and it freezes pex doesn't bust. Great video!
Thanks for clearing up my mind to use pex myself. I built a cooling system into the compressor output and it looks kinda ‘cool’ with all the copper tubing. I also have an air drier at the end to help hold the moisture to a minimum which can be brutal here in Florida summers, which incidentally last 9 months.
Hey how’s it going!? Great set up! I see this is 5 years ago. How’s things holding up? Looking to do this myself. Any tips or advice you learned after you did this?
Only thing I think I would have considered is an manifold so I could isolate lines in event of issue or if I needed more volume to a tool. Was that a consideration?
Ps. Stop being so damn insecure and constantly defending your choices, just rep your shit and post it, let the haters hate... your install looks good and clearly works for you, that's all that matters... Thanks again
I actually used pex for upgrading my house which used to have galvanize piping and some copper. I ripped it all out and put in pex. Yes having the right crimps and the tools makes all the difference. I actually have the crimping you have. Lol works wonders.
A Whole Lot Of The Problems I've Heard Of People Complaining About PEX Type Pipe Is Due To The Old Stuff; I Admit I Had Problems With Some Of The Old Stuff, But The New Stuff Is Awesome & Easy To Use & More Important To Me Is Its EASY TO REPAIR If You Ever Have To☺!! Great Job & I've Enjoyed Watching Ur Vids!!
Why not Type L copper? I used that in my shop, did it myself, and in 15 years had zero problems running at 125 PSI... Also where you stub out your air connectors if you throw a 90 (pointed down) on before the adaptor the hose will connect and not stick out into your shop space and virtually eliminate a snag hazard
How do you like how your pex system is holding up after 2 years, anything you would have done different ? Wanting to do this for my shop and trying to decide what clamps to use. What would you suggest, the rings like you used, the stainless pinch clamps, or the sharkbite push to connect? Also what size pex would you recommend running, I have a 2 stage 5hp ingersoll rand compressor.
We use poly flow tubing which is basically the same thing and works awesome fast and cheap to install. awe run it with a rotary screw compressor and have no issues 5 years and going and live in the north east with extremely cold winters no issues. Looks good
I've always wanted to try this but I kind of need at least three quarter inch line at 175psi. I wonder if it would hold up long term. It looks like temperature affects the max PSI for this stuff
Hey Dan, What fittings did you use at the quick connects? Drop ear elbows? What are the stub outs and type of nut connector used? Compression fittings? Great Vids!!
For fun Dan you should have upset the whole world and Sharkbited the whole thing. LOL Nice clean job. Bravo. btw I have a piece of Uponor A pex under the hood of my Dodge truck on the emission vent line from the aircleaner accordion hose to the valve cover. Certainly not an approved use but it works and is holding up well under there. Chrysler wants 14 beans for that molded hose. NOT.. Pex rules the world..LOL
I have a bunch of Pex stuff leftover from the replum of my house. I had planned on returning it, my plans have now changed. Thanks for doing this. Also, do you use any type of dryer on your system? Also what size tubing are you using?
i used 3/4" for the main run that is most of the Blue stuff, then i used 1/2" for the legs that run down to the plugs, that’s the red stuff, i used these sizes because that is what i had left over from previous projects. I don’t have a drying installed, when I need dry air I have one of the plugs that has a moisture separator on it.
Hey Daniel, I am in the process of planning to install air line in my shop. I though I would do a little more research an came across your video. Thank you for doing the video! You have inspired me to do exactly what you have done. Just like you I have extra material from a previous job. I'm glad I watch your post. Thank you! Did you use all 1/2 inch or 3/4 pex pipe? Plus was there any special type of pex pipe or brand that's best to use? Thanks again, David Hope all is well
David Brousseau Are used much 3/4 I had, then I switched over to have inch. The stuff I use was just the stuff you buy at Home Depot. My system has been installed for over year and a half it’s always been pressurized I’ve never had any problem with it.
I know this is an older video, I'm planning on doing the same thing and was wondering if you have any advice on what worked/didn't work? Did it work to drain the moisture from the one line you installed or should I put in a lower drop to catch moisture? Any help/advice would be greatly appreciated, thank you for making the video!
have had the system pressured for a long time and have not had any problems with it. As for the moisture my shop is isolated and heated, so i don’t have a lot of moisture problems with the air system. Every once in a while i use a regular air blower on the out lets and just let it flow for a min or so, and it blows anything out that is in there. the time and expense that would have been required for a moisture drop leg or a loop was not worth it to me. Also for the few times that I have a tool that really requires not moisture in the line I use a dedicated out let that has a moisture separator on it, that I picked up a harbor freight.
@@DanielWoodellI've heard other Tubers mention failures with crimp style PEX, and from what i've heard the Uponor is preferred for water, how do you think it will fare with air?
Chris Woolvin Uponer is a great product much better than crimps, down side is it’s not sold at Home Depot or Lowe’s and the tooling is expensive, if it was readily available I would have used it.
Jealous of that mancave, Daniel. Question: are you concerned at all about sheetrocking over the PEX? If you end up having a leak, at any one of your connections, it might be difficult to find the source and then have to tear out all of the sheetrock. Other than that, it looks like a great setup. Haven't watched all of your videos yet but did you put insulation in between the studs and sheetrock? Cheers.
@Daniel Woodell will you please share the various types of fittings you used to make up your manifold stations/air adapter? I took a close up pic and shopped the internet unsuccessfully. Thanks.
This is awesome! Literally just googled the exact words of the title of your video bc I have a bunch of pex leftover from a project and wanted to use it for air drops as well... saw this video and it just helped validate my thoughts along with some other research but I am with you my friend, I just don't see why this wouldn't hold up just like any other plastic tubing out there used for air lines... so long as you keep it protected from uv since that will deteriorate it... Great video tho and thx for the info! Looks great btw! Cheers! - Jesse
well I was just going to use 1/2" copper pipe, an like you I don't see much of a difference. I am not going to price out a PEX install, cause I never thought of it before. Thanks
Man this is awesome! I always wondered why people weren't using PEX. I understand your system pretty well, but I have a few questions. Could you go into a little more detail as to how you put together the air manifolds where you hook your tools up to? Also, what did you use on the threads for the air tight seal when putting together those manifolds? Thanks Dan! Awesome system.
Good video. My garage stays from 95 to 102 degrees in summer (Texas normal). The attic stays around 140 to 150 with ventilation. In your experience how will the pex hold up to these conditions ,on the long term, running through the attic down into the garage?
"In accordance with ASTM F876 Standard Specification for Cross-linked Polyethylene (PEX) Piping, the excessive temperature and pressure capability for Uponor AquaPEX® is 210°F (99°C) at 150 psi."
PEX works great. I suspect that people are nervous because there have been some horror stories involving the use of PVC. PVC is notch sensitive. So even though it may be rated for the pressure if you drop a wrench on the PVC pipe it can easily explode! But PEX is somewhat flexible and will do just fine. It is not rated to exposed to sunlight however so just don't run it in front of a window.
@@enzprintco.8625 It might but the question is, will the solvents of the coating affect the integrity of the PEX? Personally if you needed a UV resistant solution I would run it in copper. If it was just a short length in front of a window then you could use a length of larger diameter PVC pipe and simply slide the PEX inside the PVC to block the sunlight.
Frank Hinde are there any stories of pex bursting on an air line? I was thinking like that flex seal or plasti-dip to coat the pex...so if it explodes, won’t send shrapnel everywhere ?!?! Sorry, super new to this. Got a new Quincy 60 gallon compressor and still trying to figure out the best setup for paint. Thanks for the info!!! :)
@@enzprintco.8625 No stories of PEX bursting.. Even if it did it would split, rather than shatter like PVC will. So its perfectly safe in that regards. But no I would not paint it with anything, especially not a solvent based paint which could well weaken the PEX. PEX is rated to a pretty high pressure from memory, but remember that any plastic pipe gets weaker as it gets hotter. I am a professional engineer with 30 years experience and I have occasionally seen flexible plastic tubing fail where it has been run inside machines where it gets really hot. But honestly its highly unlikely you will have that problem unless you run it behind an electric space heater for example. Just keep it out of direct sunlight and it will be a great solution for you. Put it this way.. I ran my compressed air distribution system in PEX and its been there for more than 10 years..:)
@@enzprintco.8625 Oh your are intending to use your setup to spray automotive paint?? Honestly your biggest potential issue is oil carryover from the compressor itself. If you get the SLIGHTEST amount of oil in the compressed air you will get fisheyes in the paint.. It looks HORRIBLE! I have painted 4 cars and one airplane. The way I solved the issue is to buy an oil free compressor. My Craftsman compressor cost $300 back in 2005. Now they have a reputation for not lasting long but the paint cost for the airplane was over $1000, so $300 for a throwaway compressor seemed like a good deal. I still have that compressor today and it runs great. Now even if you run an oil free compressor, if you have used your air lines on a previously oily compressor, even the oil contamination in the airlines will be enough to give you fisheyes.. I know this from painful experience! Most people use an oil filter and seem to get OK results. I personally just went the oil free route.. i.e no oil = no fisheyes period. But if your Quincy is oil lubed you will need to take precautions against oil contamination.
What's funny is you say that paix is not supposed to be used for air pressure, but there's another video where a plumber said that paix is all that is used in current air systems. I plan on using it as well.
I would have a higher connection on the wall and make a shelf for the compressor to sit on and connect. Get stuff off the floor when you can and have tall walls.
Shawn Vandenabeele If you use the expansion type connectors which is what most the pros use most they cost is in the tool then so if you do enough fittings it pays it's self off. The expansion type connectors are just about the same price as copper.
By any chance were you using Pex A or Pex B? I know Pex A has a thicker wall and should hold a higher Psi. My compressor is rated at 150 Psi and Pex B is easier to find at you big box stores, so will Pex B hold??
Matt Risinger texted a few his only sample of PEX A Uponor failed at 425+ & the PEX B's all failed 800-1050 PSI. Any pex will do for air systems with a healthy margin of error.
@@nickp9981 Yes thats at room temperature. My professional engineering license (currently retired) forces me to point out that you must not run it behind say a space heater. All plastic pipe's rated pressure falls considerably with higher temperature. And not in direct sunlight either, so don't run it behind a window that gets direct Sun. Other than that PEX is a great solution. I have had mine in place for close to 15 years now.
@@frankish5314 even at tempeture I would guess that pex holds enough strength to be near heat systems , I would say the big issue is to cool the air down before putting it into the pex as a compressor running full out can leave the first section of hose real hot. I have run a system for a few years the first part of my air system is through a coper tube coil that goes into a large plastic drum filled with water that cools the air down to "basement tempeture" and also dries the air. The real issue is the direct sunlight or for that mater any UV light (like from florecent bulbs) will slowly damage and destroy pex cover it all.
@@nickp9981 A quick Google search gave me ASTM 877 ratings as follows. 160psi@73degF. 100psi@180F and 80psi@ 200F. Of course these are rated pressures. The burst pressure will be higher than this but no engineer that doesn't want to get sued would suggest you go beyond these values.
@@frankish5314 in the tests done by MS mentioned above the burst pressure was 800+ for all pex b, for a domestic compressor thats likely around 120-150 max psi there is more then enough strength.
@@enzprintco.8625 Idk why he'd have to reply to every comment someone asks him this. He already replied a few months ago to the same question: "Its working great it has been pressurized fro years at this point and i have never had a problem with it."
Please provide three examples of times you would need 175 PSI. I would say for those limited times, you could run a hose straight off of the compressor. Your average DIY home enthusiasts are not going to need pressures above 90 PSI.
see below link, however you can find this stuff at any big box store, that is where i got the stuff i used this is the tool www.amazon.com/SharkBite-23251-Crimping-2-Inch-Fittings/dp/B007AGMM1W/ref=sr_1_8?ie=UTF8&qid=1517717651&sr=8-8&keywords=pex+crimping+tool these are the crimps www.amazon.com/SharkBite-23103CP25-Crimp-Rings-4-Inch/dp/B007AGMFF0/ref=pd_bxgy_60_img_3?_encoding=UTF8&pd_rd_i=B007AGMFF0&pd_rd_r=4A01HY4ESCYEQ5F887RH&pd_rd_w=iCbKd&pd_rd_wg=29CtC&psc=1&refRID=4A01HY4ESCYEQ5F887RH
Thanks Dan, I found these at Home Depot. Some reviewers mentioned that these crimps fail the go-no go test about 1 in 5 - did you find that to be the case?
vahpr the only time I have had problems with failing the go no go is when , I was not able to keep the crimp tool at 90 degrees to the pipe, this other videos shows that a little th-cam.com/video/l9NwZC85S0c/w-d-xo.html
You're high in the night! NO PEX works for that kind of pressure especially when it's hot! 150 psi is about the limit @90°F. After that you're living on borrowed time!
@@wesman7837 your talking about the manufacture rating. Totally different. I’ve seen them tested. It takes a lot of pressure to break them. The manufacture rating has a safety factor in it. I’m sure you can find a video on the tube with it being tested if you want.
Dan, The electrician perspective is that a static discharge wire should be used to prevent drawing an arc when connecting to the air chucks. The shop environment is ripe with potential explosive hazards. I saw your video well after the original installation. I would consinder retrofitting your air system. Also I am would recommend you retrofit the vertical air lines with a drain port.
Mr. Fartbox Ohyeah, I am the .001% that witnessed a magnesium fire in a machine shop from disconnecting an air chuck drawing an arc. Respectfully I am not changing my opinion.
Oh my gosh I can't believe you used PEX, I mean just think about it moisture gets in those lines and it won't even rust them out overtime and with it being a plastic vibrations won't even create any weak spots. What a terrible idea. Tear the whole building down and redo it
Only because i was using up left over material form a previous job, but 1/2 is more than adequate as the restriction in the QD air fittings is much more restrictive than the 1/2" PEX
Its doing great it has been pressurized, from about a week before this video was posted and i have not had a single problem with it, in fact im getting ready to insulate and sheet rock the walls.
Any issues now that it has been over a year? And OMG WHY ARE YOU USING PEX FOR AIR GAAAAHHH lol j/k I left all my pex tools at our old house (now renting it out) 1000 miles away because we moved into a brand new house that I'll not have to redo all sorts of plumbing on (fingers crossed).
4:50 Instead of talking so much you could rather have measured it properly and save a connector. And i do agree that PEX-AL-PEX is a great option and my choice for air plumbing. We can get it here with 10 and 25 bar rating. Did it leak or not?
Omg why did you use pex it is sooooo dumb!!! Just kidding 😂. Don’t understand why it matters to other people what he puts in his own shop??? Your not the ones that love with it. Let the man do what he wants to do with his own shop. If you don’t like it, than don’t use it!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

But no I would not paint it with anything, especially not a solvent based paint which could well weaken the PEX. PEX is rated to a pretty high pressure from memory, but remember that any plastic pipe gets weaker as it gets hotter. I am a professional engineer with 30 years experience and I have occasionally seen flexible plastic tubing fail where it has been run inside machines where it gets really hot. But honestly its highly unlikely you will have that problem unless you run it behind an electric space heater for example. Just keep it out of direct sunlight and it will be a great solution for you. Put it this way.. I ran my compressed air distribution system in PEX and its been there for more than 10 years..:)
@@enzprintco.8625 Oh your are intending to use your setup to spray automotive paint?? Honestly your biggest potential issue is oil carryover from the compressor itself. If you get the SLIGHTEST amount of oil in the compressed air you will get fisheyes in the paint.. It looks HORRIBLE! I have painted 4 cars and one airplane. The way I solved the issue is to buy an oil free compressor. My Craftsman compressor cost $300 back in 2005. Now they have a reputation for not lasting long but the paint cost for the airplane was over $1000, so $300 for a throwaway compressor seemed like a good deal. I still have that compressor today and it runs great. Now even if you run an oil free compressor, if you have used your air lines on a previously oily compressor, even the oil contamination in the airlines will be enough to give you fisheyes.. I know this from painful experience! Most people use an oil filter and seem to get OK results. I personally just went the oil free route.. i.e no oil = no fisheyes period. But if your Quincy is oil lubed you will need to take precautions against oil contamination.
What's funny is you say that paix is not supposed to be used for air pressure, but there's another video where a plumber said that paix is all that is used in current air systems. I plan on using it as well.
I would have a higher connection on the wall and make a shelf for the compressor to sit on and connect. Get stuff off the floor when you can and have tall walls.
I use the Upinor expandable rings instead of hose clamps, wrappedin tape(to protect from UV rays), on my air compressor hoses
"TAKE A DEEP BREATH"!! IT,S ALL GOOD"!!! JUST LIKE YOU"!!
Air supplies can freeze if you running pipe in cold area
awesome video well done mr dan,love pex my self aint bad priced but them dam connectors boy they can be costly.
Shawn Vandenabeele If you use the expansion type connectors which is what most the pros use most they cost is in the tool then so if you do enough fittings it pays it's self off. The expansion type connectors are just about the same price as copper.
By any chance were you using Pex A or Pex B? I know Pex A has a thicker wall and should hold a higher Psi. My compressor is rated at 150 Psi and Pex B is easier to find at you big box stores, so will Pex B hold??
Matt Risinger texted a few his only sample of PEX A Uponor failed at 425+ & the PEX B's all failed 800-1050 PSI. Any pex will do for air systems with a healthy margin of error.
@@nickp9981 Yes thats at room temperature. My professional engineering license (currently retired) forces me to point out that you must not run it behind say a space heater. All plastic pipe's rated pressure falls considerably with higher temperature. And not in direct sunlight either, so don't run it behind a window that gets direct Sun. Other than that PEX is a great solution. I have had mine in place for close to 15 years now.
@@frankish5314 even at tempeture I would guess that pex holds enough strength to be near heat systems , I would say the big issue is to cool the air down before putting it into the pex as a compressor running full out can leave the first section of hose real hot. I have run a system for a few years the first part of my air system is through a coper tube coil that goes into a large plastic drum filled with water that cools the air down to "basement tempeture" and also dries the air. The real issue is the direct sunlight or for that mater any UV light (like from florecent bulbs) will slowly damage and destroy pex cover it all.
@@nickp9981 A quick Google search gave me ASTM 877 ratings as follows. 160psi@73degF. 100psi@180F and 80psi@ 200F. Of course these are rated pressures. The burst pressure will be higher than this but no engineer that doesn't want to get sued would suggest you go beyond these values.
@@frankish5314 in the tests done by MS mentioned above the burst pressure was 800+ for all pex b, for a domestic compressor thats likely around 120-150 max psi there is more then enough strength.
i love pecks ill never go back to copper , nice building !
Hey bud. How has it held up?
Thanks!
:)
?
@@enzprintco.8625 Idk why he'd have to reply to every comment someone asks him this. He already replied a few months ago to the same question: "Its working great it has been pressurized fro years at this point and i have never had a problem with it."
TheBreaded k
110 psi? I want to be able to run at 175 psi when I need it.
Please provide three examples of times you would need 175 PSI. I would say for those limited times, you could run a hose straight off of the compressor. Your average DIY home enthusiasts are not going to need pressures above 90 PSI.
PEX is the way to go.
You talked me into PEX for my new shop :) What crimp tool and crimp type did you use? Thanks, great video.
see below link, however you can find this stuff at any big box store, that is where i got the stuff i used
this is the tool

Thanks Dan, I found these at Home Depot. Some reviewers mentioned that these crimps fail the go-no go test about 1 in 5 - did you find that to be the case?
vahpr the only time I have had problems with failing the go no go is when , I was not able to keep the crimp tool at 90 degrees to the pipe, this other videos shows that a little

Pex ,even the cheapest one breaks above 500 psi. Some of them break above 750 psi.
You're high in the night! NO PEX works for that kind of pressure especially when it's hot! 150 psi is about the limit @90°F. After that you're living on borrowed time!
@@wesman7837 your talking about the manufacture rating. Totally different. I’ve seen them tested. It takes a lot of pressure to break them. The manufacture rating has a safety factor in it. I’m sure you can find a video on the tube with it being tested if you want.
why not use the roll, less joints
You can use a roll but it never lays out perfectly straight like the straight lengths do. Just an appearance thing.
Dan,
The electrician perspective is that a static discharge wire should be used to prevent drawing an arc when connecting to the air chucks. The shop environment is ripe with potential explosive hazards. I saw your video well after the original installation. I would consinder retrofitting your air system. Also I am would recommend you retrofit the vertical air lines with a drain port.
Mr. Fartbox Ohyeah,
I am the .001% that witnessed a magnesium fire in a machine shop from disconnecting an air chuck drawing an arc. Respectfully I am not changing my opinion.
@@steverosenbaum2469 magnesium from what? There is no risk of fire from the compressed air unless you are adding something flammable to the system.
Pex is a great product, if it works it works
Oh my gosh I can't believe you used PEX, I mean just think about it moisture gets in those lines and it won't even rust them out overtime and with it being a plastic vibrations won't even create any weak spots. What a terrible idea. Tear the whole building down and redo it
Great job but why not run all 3/4" pex?
Only because i was using up left over material form a previous job, but 1/2 is more than adequate as the restriction in the QD air fittings is much more restrictive than the 1/2" PEX
What would be better the blue pex or red (hot water) pex
I think it's all the same. Also sold in white and clear.
There is no difference that I'm aware of.
What is your favorite color blue? red? that is the difference lol
How's the pex holding up so far?
Its doing great it has been pressurized, from about a week before this video was posted and i have not had a single problem with it, in fact im getting ready to insulate and sheet rock the walls.
I’m looking at a little different, all that effort 3/4 fitting would cost not much more
Any issues now that it has been over a year? And OMG WHY ARE YOU USING PEX FOR AIR GAAAAHHH lol j/k I left all my pex tools at our old house (now renting it out) 1000 miles away because we moved into a brand new house that I'll not have to redo all sorts of plumbing on (fingers crossed).
Nope no issues at all!! and the air system is working great also!!
4:50 Instead of talking so much you could rather have measured it properly and save a connector. And i do agree that PEX-AL-PEX is a great option and my choice for air plumbing. We can get it here with 10 and 25 bar rating. Did it leak or not?
Looks good
I think it's a nice idea I know it works good I like to be different too 👍
Hows the pex air system working?
Its working great it has been pressurized fro years at this point and i have never had a problem with it.
@@DanielWoodell Same here.. More than 10 years.. Actually nearer 15 now I think about it. Works perfectly.
You right Chris
Nice dog
Omg why did you use pex it is sooooo dumb!!! Just kidding 😂. Don’t understand why it matters to other people what he puts in his own shop??? Your not the ones that love with it. Let the man do what he wants to do with his own shop. If you don’t like it, than don’t use it!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
Too expensive to do just one such job when othesr are cheaper and work very well.
OMG WHY DID YOU USE PEX?
Viral Awakening he said it on the video, cheaper, looks better, easier to install
PEX works great for airlines.. Mine has been in place for more than 10 years.
Good Lord man ! LOL
Because he's only running his pressure at 110 psi.
