Thanks in advance for taking the painstaking, time consuming task of figuring out less costly solutions for different pressure washers. Even though you might have a monetary gain from doing so, I am sure it’s not something that you are passionate about doing. So I, and I am sure many others appreciate the effort you are putting into this and doing this for us. ( you truly are evolving lol) I am not a professional detailer, just a guy that enjoys detailing and keeping their vehicles looking nice. It’s not that I can’t afford a $1200 pressures washer, It’s that I can’t justify buying a $1200 pressure washer. I wash my cars maybe 20-25 times a year, and I can’t wrap my head around the fact that the Kranzle will make my car wash experience that much more enjoyable over say a AR Blue. I have the rupes mark ll, tub of microfiber and two shelves of products, it adds up. Actually I don’t even want to think about how much it would add up too. I do look forward to videos of other more affordable options, thanks again.
Although, I'm largely chasing the passion and sharing the products that I have the most interest, I do see those that aren't able to at this time or maybe just don't value an expensive pressure washer as my future long-term customers. Those that are willing to upgrade those machines to improve the experience will likely also be interested in other things I have to offer as well.
@@ObsessedGarage ran across your channel when I was searching for the different tip sizes for different pressure washers and I was searching because I was told to never use tips that were from others and only use the one's that comes from the same company that is the maker of the machine because it will void the warranty ( like on the Sunjoe 3001 model, I don't use it for cars, I use it for cleaning the siding on my house , but good video
I realize this was made a couple years ago,just want to thank you for all the info you supplied in this video, it has helped shed some light towards me getting some understanding of pressure washers and how to use them.
Thanks and keep on keeping on.
Thanks Austin.
U r the man... If any question comes in my mind i just check ur videos and find the answer.. Keep it up.. Thanks from kuwait
Great video Matt! Appreciate all the info you provide!
Hi Matt, Great Video, Love all the details! I am a Mechanical Engineer and the details means allot to me.
Wow! Yes thanks for this information. I have a 3200psi and 2.5gpm gas pressure washer. It was not purchased for washing cars but for projects around the house.
However, I have been wanting to add washing our cars to things the pressure washer can do. I used the supplied 40 degree tip and gun that came with the pressure washer. But, in the back of my mind, I thought it was to much pressure.
So, I ended up ordering the MTM Hydro gun and wand kit and after watching this video also ordered a 4.0 and 5.0 nozzle to see which one feels better and safer for use with my pressure washer. The larger the hole in the nozzle should bring the pressure down to the preferred 1000 psi. Hope it works!
How did it work? Did it bring the pressure down for you?
Great videos brother! Always enjoy them!
Thanks man!
Excellent Matt! This is important information.
Thanks man.
Thank you for taking the incredible amount of time it took to put this video together. It was very informative and very helpful. I hope to have an Obsessed garage power washer system someday.
Thanks man.
I am technical type of person and definitely enjoyed the video. My pressure washer was given to me by my dad along time or I would probably already have a Kranzle K1322TS. Mine lacks ts which is something I would really like to have. But other than that it seems pretty dam close to the output of the Kranzle ( my neighbor has the K1322TS). I just thought I would put it out there as a option for people who can't spend 1k.

"..and I am picking up the e92 in about a week"..same excitement level this morning when I found out my milk hasn't expired. So calm, cool, and collected
Ha, ha... With the reliability of shipping companies, it's likely going to be more like a month.
You found your unicorn e92 already?? I’ve missed mine since I I got rid of it… Have a feeling I’ll be missing it a lot more very soon. Congrats! Can’t wait to see it
Hopefully this is relevant. I have a gas powered Ryobi 2800psi 2.3gpm pressure washer. I've been using your 4.0 40° orifice. On my pressure washer it felt like I had too much pressure. Last week I bought a 4.5 and 5.0 40° orifices. After trying both I've decided to stick with the 5.0. I haven't been obsessed as you and I didn't test it scientifically with a gauge but I'm happiest with the feel of the 5.0
That's how I've been doing it for years, by feel. This is the first time I put a gauge on it to get an idea of the pressure I'm getting.
I used your video to figure out a 5.5 size nozzle would be the best option for my 3100 psi 2.8GPM gas motor, I wanted a safer tip for washing my car and this video helped me figure out what I needed to get to ~1000 psi according to your ratings the old tip was a 3.0 tip and supposedly would dump 3400 PSI but the unit is only rated for 3100 so I get what you mean by saying that there's some efficiency loss when the motor can only bring out so much, in other words the motor is a bottleneck for the system, makes sense, but your chart works great for down shifting the numbers.
Thx matt. Very detailed and informative. 👍
VERY Educational..ty!
I have an E92, like the one you are picking up, sanz the carbon roof (I wanted a sunroof). But, I’m on a blue-collar budget…a few Dinan parts is all I have….I cant wait to see what mine could be if I had unlimited funds…E92! E92! Let me live vicariously through you! SHOW THE E92!
Ha, ha... I just ordered the Eisenmann Black Sport and Macht Schnell catless center section yesterday from IND.
Can’t wait for that prototype nozzle
Put me on the waitlist!
On my Karcher K7, wich is rated 10l/min and 160bar maximum, i made a test, i collect the water in one minute to see if i collect 10l. First, with machine on without a nozzle, i collect 10l, second i put the nozzle and i collect the same amount, 10l. difference was that with nozzle, the pump will delivery more bar, pressure.
Hello guys.
I have a nilfisk Pressure washer with 190bars max pres and 650l/h max flow.
The correct nozzle for this is the 3.5 but i already have some 3.0s.
Is the 0.5 difference big? Will i overstress the motor? Should i buy the 3.5?
Thanks! :D
Great video Matt and this information came right on time. What would we do without you.👌👌👌
you missed a chance to let us know about Bernoulli's equation :). Also we can look at motor power rating, PD pump power equation & power loss across an orifice. Seriously though, great video!
Great video.
I have Karcher K3 full controll. 1600psi. Max 120 bar.
Can I use 2.0 or 2.5 , 3.0 ?
Thanks I had no idea!
So the gage was measuring back pressure in the line.., probably why when attempting to shove the same force (horsepower) and flow (gpm) from 6.0 through 4.0 orafice back pressure increased. But does pressure at the face of the nozzle change to almost that gage pressure reading or if not, does it actually almost double as observed here?
What is the impact at the front of the nozzle, after the water actually traveled through the main variable that changed... the orafice. is there a way to measure or calculate that i wonder. (load changed so how motor responds is another of probably many variables).
I totally understand selecting the correct size orafice to put the right load on your pump that makes sense and is shown by the gage test.
Thanks for the video.
Great video, and I love the details and not rushing it along !! I have a Karcher K5 which I believe is 1.4 gpm and 2000 psi, so would my oriffice choice for nozzle tips be 2.5 ? Thanks....newbie here
The 2.1 or rated gpm is the max output of the motor (HP) and pump at max current flow of supplied voltage. A 0 degree nozzle equals 100 percent output, 15 degree nozzle decreases output by 70%, 40 degree by 88%, according to Krenzle. An orifice just increases or decreases back pressure on the pump, which can make the pump work harder, create more heat, wear, etc. It is best to stay near the recommended orifice size of the manufacture. A pressure washer is a PD pump, max output is max output, as Matt said there is no way to increase the Max Output.
Yet another great video, so much info & explanation. Just what I needed :)
Hi Matt, I bought a Kranzle K2160 TS rated at 11 l/min and 2000psi, based on the chart, states that I should use 4.0 Nozzle. am I correct?
but how about if I want to adjust the pressure washer pressure regulator to 1800 psi?
This reminded me of an online lecture for one of my classes 😂
I feel your measuring back pressure
Hello I have a karcher HD 585 that has the following specifications:
Water Flow (l / h) 500
Pressure (PSI / bar) 2100/145
I do not know which measure of Pressure Washer Nozzles, to buy could help me.
Thank you !
Great video Matt!! But question/opinion...I have the SunJoe spx4001 that is rated at 2030psi @ 1.76 gpm. I just looked at the nozzles it comes with and they are stamped with 9.5...wouldn’t that be to high for that pressure washer you think? Possibly a mistake of sorts? Thanks in advance...
There is no way those are 9.5 sized nozzle. The SunJoe will be the first ones I'll be testing. MTM just sent me the photos of the prototype Kobrajet 1/4" hose, so the project is coming along.
Obsessed Garage that’s what I thought too, but that’s what they are stamped...I checked all the nozzles. It threw me off, so I went as far as emailing Sunjoe...waiting to see if they respond.
I have a kranzle 2160tst which nozzle can I choose for my pressure washer?
Great video, man I was kind of hearing myself in my head when you talked about the progression and the difference things. That's what I commented on your Sun Joe video as that's the route that I took. 200% agreed man, all about progression, great the idea about more packages, no question Kranzle is far superior in every way, but an inexpensive Sun Joe spx3000 for example, will get the job done for anyone thinking of getting into foaming with a pressure washer, plus it's way better than a garden hose and foam gun. If I understood correctly, you're going to offer the prototype nozzle in different orifice sizes?, hope that's the case, because I'm getting them for sure. I got the mtm swivel from mtm for the SG28 complete package I got from you and IMO having a swivel is a must, I maybe regretting not getting at least SGS28 or the mosmatic gun right away, but hey, it's all about progression, trial and error. It's not really what's the best and expensive, if it fn works doesn't matter to me if it is expensive or not, if that's what I want. Keep doing crazy man, for sure you're making us car guys/enthusiasts life easier with what you are doing. BTW, I'll bet you gave that ceiling a good clean 🤣🤣🤣
The new nozzles will come in different sizes and degree spray patterns. It will also fit on any standard 1/4" coupler, so it will work on any gun.
@@ObsessedGarage awesome, thanks
It’s would make sense to use tip size that gives you the same PSI as the factory wand? Not less, not more as it affects the unloader? Creates increased wear and tear? So I’ve been lead to believe..
Is the MTM foam lance out of box ready to use at kranzle ,or you have to modify noozle inside bigger -smaler?? Thank you
The 1.25mm orifice is what I use, but that will work the pump harder. You'll pull almost 18A, so you really need to run it on a dedicated 20A circuit. If you move to a 1.5mm orifice, then you can run it on most 15A circuits.
You should offer that gauge setup in your store :) I'd buy it!
You just settled it. I'm ordering them to add.
Northern tool or pressure pro have it ..
I have a Simpson pressure washer 3200 Max psi 2.5 GPM Wich orfice do i get to get more water flow ????
I have a Ryobi electric power washer. 2000psi and 1.2gpm. What size orifice should I get? I’m using a 2.5 orifice nozzles now but I need more water flow. So should I get 3.5 or 4.0?
2.5 is the correct size. Your pressure will drop way to low to be functional with a larger orifice.
I have the same pressure washer stats. So 2000psi and 1.2gpm. If I get a 2.0 size orifice that will be to small?
I have kranzle HD 7/122 pressure washer . Which nozzle is perfect.
Nozzle size and gpm of nozzle
130 bar. Pressure washer. Looking charts it looks either 0.25 or 0.3. Cannot decide. Is there any issue going larger. It is 1875psi 130 bar. Thanks
I have the Karcher cube I want to use the 40 degree nozzle tip what orifice do I need to use on the 40 degree tip ?????? Plz help
Whats up with tge crazy bird in the bacground? That woukd drive me insane. Lol Thanks for the great info!!
It would be interesting to do a test by putting a current meter on the pump and document the current draw with different nozzles?
Obsessed Garage is gonna be the go to for detail products
Already is in my book! Just looking forward to the product selection increasing over time
@@youngblood23rb me too
indeed
That's the plan. As my volume increase, my shipping costs fall to make offering more economical shipping cost for people purchasing.
@@ObsessedGarage awesome! Can't wait
So Matt the big issue would be when we use the c.r filters they say do not exceed 2.5 gpm or the filters can not keep up and clean the water. So if I have a pressure washer that is rated at 2.8 gpm I need to slow that flow down in order to use the filter but pressure is the enemy when using for washing cars so how would u slow down the flow without increasing the pressure. I look at it like a transformer voltage goes down but current goes up if current goes down voltage goes up so I need to find a way to build in losses somewhere almost like Eddie currents or core losses in said transformer. This of course untill I can buy a custom setup from u.
If you're pump has an unloader valve, you could divert some of the flow.
I have a Cat pump 3000 PSI 2.7 GPM should I ve using 4.0+ and up
what size i need for kranzle 7-122 HD europe ? I want to use it for mobile pressure washer : what orifice i need ?
I've an electric powered Karcher K5 600, not sure if its spec is accurate,
140bar (2000 psi),
460L/h (2 GPM)
so does that mean I should get nozzle size "3"?
Yep. A 3.0 nozzle would work for you.
Question, so we should use the nozzles to change the PSI... do we leave the valve on pressure washer open all the way?
You have that correct.
So I can’t use 3.0 orfice on Krānzle 1622 ts? Got it from detail division he said to go 3.0 and not 4.0
Get a Fluke Amp Meter and clamp it around the power cord to test the pumps load with various nozzles, would be interesting
I was just thinking about that last night. I just ordered one.
Hi Matt,
I just bought a new pressure machine (Kranzle pump K1622 1.600 / PSI 1.6 Gallons per minute) in Canada. I have a Mosmatic swivel rifle (purple), MTM Foam Cannon PF22 personal washing tools that I love. Now I have to buy new nozzles. What numbers do you suggest to me not to damage my new pressure machine? I love to follow your videos, I'm a fan of Obsessed Garage. Excuse for my bad English writing, I am a French Canadian from Quebec.
Thanks you for answering my questions.
Pierre Rémillard
According to most standards sheets on the internet, the choice of nozzles should be (2.5 or 3.0). I prefer your opinion, you know the pumps Kranzle K1622.
4.0 is what you need for the 1622.
Ok, so I’m going to try the 1.1 orifice on the amazon foam canon and also grab a mosmatic handle with the nozzle set for my k4 from your site. If the foam improves, I’ll stick with that setup. If not, I’ll grab the mtm canon. Thank you for making this understandable and readily available. I’ve learnt a lot from your videos.
I have a generic chinese washer rated at 150bars and has a pressure guage mounted on top. It came with a green tip, i believe it is a 1.5 to 2.0gpm nozzle and the guage read 250kg/cm2, i then upgraded to a similar nozzle but at 4.0gpm and the readings went upto 350kg/cm2. Is this good or bad ?
That is a very substantial increase in pressure and flow. What size orifice nozzles are you using?
@@ObsessedGarage I really can't say, both suppliers have no info and are unbranded generic green nozzles. That said I have been observing them and i can only see a slight difference in the orifice sizes. I got some pics and vids if that helps.
So, if I'm reading this correctly, if my pressure washer is rated for 3800 psi and 3.5 gpm, and I wanted ~1000psi I would select a 6.0 nozzle, right?
Correct
@@ObsessedGarage thanks for the feedback! I'll be placing my first order from og soon! 👌🏻
Have you considered working with MTM to offer a 4-pack of 40 degree 4.0 nozzles? I know for me, using your Complete Pressure Washer solution, I would like to have a few extra white 40/4.0 nozzles on hand but don’t really need the other varieties. Looking forward to your prototype nozzle being released!
Done! www.obsessedgarage.com/collections/pressure-washing/products/mtm-1-4-stainless-nozzle-4-pack
Matt, perhaps I miscommunicated what I meant. I was meaning a 4-pack of ALL WHITE (40 degree) nozzles. The pack you linked to does have one white one, but also a red, yellow, and green nozzle. For those of us using the Kranzle mostly for car detailing, the white nozzles will get the majority of the use, so it would be sweet to have the option to buy only white nozzles in bulk. Just a thought....
That's a good idea too.
hello, I have a comet static 1700 extra with 2175psi and 172 gp / h is 2.86 gpm, I have to take what? nozzles of 4 or 3.5. thank you for your answer and continue I love your channel . Jérome 🇫🇷
2.9 needs a 6.0 nozzle.
3.5 or 4 is good then?
You will get a lot of pressure at that small of an orifice. I would suggest going with a bigger 6.0. That will get you around 1000PSI.
I have 2175 psi and 2.86gpm . so in the table I find 4 or 3,5
ok thank you, I will follow your advice, I order Monday. Thank you for your answer🙌🏻
Matt, you better be careful! You're gonna hurt all these instagram heroes' egos when they realize their favorite 15 degree tip is actually dangerous like everyone's been telling them!
Two suggestions for you:
1.) In the fire service, gauges like you showed are often inserted inline to the hose just before the appliance (nozzle) to measure pressure and flow as close to the tip as possible. This is because of the friction loss through the hose and couplings. You may want to consider moving the gauge to the output QD with the nozzle directly in the output of the gauge to take into account the additional loss of the gun itself. The gauge would then be reading effectively the 'back pressure' or the pressure being exerted back on the gauge from the restriction of the nozzle.
2.) Regarding burning out the motor, you should be able to put one of those wall plug meters on the machine that will display the power draw on a digital display. I forget if they measure in wattage or amperage, but it's an easy conversion either way. That should show you if the draw changes any depending on what nozzle you're using. Worst case, you could use a clamp on meter on the cable of the washer itself to see the difference in draw.
Good stuff...
If iGet a bigger orifice like a 5.0Size do u think 2.0 GPM would be possible? Or atleast better than the rated1.2
Pumps have output limitations. It may not have enough power to produce pressure with that sized orifice.
@@ObsessedGarage iHave a 40° degree nozzle that says 40040 on it ,does that mean 40 degree and 4.0 orifice? If so I'm getting great GPM/psi with that. wondering 5.0 orifice would be also run reasonably like iam with the 4.0 orifice ihave currently.
Budget line. YES YES YES way to go man for taking on the burden for us under budget married guys who's wives insist on the gas station car wash being good enough
Suttner snow foam and lances. How do they rate. Thanks
They are legit. They OE the Mosmatic Gun.
I have a Nilfisk E145 with 1.8 imerial gallon per minute, 145 bar and 2100W. What nozzle size should i get for optimum use?
Did u ever fine out the answer?
Ihave the same and could do with knowing
Matt, any news on international shipping yet? I'm building out my wall mounted pressure washing solution and its been a pain in the ass. The shipping cost alone has been 150 bucks so far and i'm still not done. Its a pain in the ass to get stuff in Malaysia. It took me a month to get my fittings and couplers from ebay and now as they arrive I realise that they don't fit! I'd rather just pour my money on your store just to have the peace of mind that crap will just work when they arrive.
South East Asia, India, and South America will always be tough.
Does the fan size (40°, 25°, 15°, etc) affect these calculations?
Never mind, asked question to early?
haha the 40 deg. tip on my GreenWorks produces barely a mist a 3-4 feet away.
I appreciate it. Love my kranzle
How can I get a 3d or 2d model of this nozzle ?
You got a really nice house and landscape.. if you dont mind, what you really do for a living ?
You are looking at it. Obsessed Garage is my business.
Could you try to get in touch with an engineer at Kranzle (through skype?) that could explain the science behind and? I guess you are on their radar since you became a reseller for their product, maybe they'll be willing to educate us on this subject?
So what's the recommended size for the Sun Joe SPX3000? Anybody have any experience?
3.0 for that
Kranzle 1120t what nozzle would you recommend?
3.5
@@ObsessedGarage thank you so much bud
What happened to the Facebook group matt?
My greenworks does well with this gun.
Let me see if we can help each other out here. Pumps put out flow. Pressure is resistance to flow. By changing your orifice size , you can not overwork your pump. Pressure is equal and undiminished in all directions. See Pascals law. This means adding a wand extension will not change your pressure. As pressure increases, flow decreases, and vice versa. Pumps bypass internally when there is nowhere for the flow to go. I was starting to think by using a wider nozzle spray pattern (say 40 degrees compared to 25 degrees) my pressure would decrease, because wider spray patterns had different size orifices. But as far as I can tell, the orifice sizes on all my nozzles are the same. The sizes are partially obstructed from view by the colored tops they are mounted in. These were nozzles included with my gas powered ryobi 2.7 gpm, 3000 psi rated machine. Maybe you can help me out there. Its apparent the tighter spray patterns put out more pressure, which would mean a smaller orifice, but from what I can see of the sizes on the nozzle, they all appear to be the same
What is the difference from the 3.0 too the 4.0
The size of the hole is bigger as the number increases.
Confused here...at 21:08 you mention the wand doesn't affect the pressure? When you put the wand on, the PSI is 1800? How does a 40/25/15/0 degree nozzle get you 900psi(to 1100).
Anyone?!?!?!?!
Was the wand, it was the tip. That was a 4.0 sized nozzle.
The content of these videos are great. But try to get to the point faster and stay on point. No disrespect intended. Thank you for the video
Pressure=Force/Area
Too bad no one makes an affordable inline flow meter.
Sorry I was thinking high pressure. You do not need high pressure. One that will work on a garden hose is good enough, because you can measure flow anywhere in the system and it won't matter, including before the pump. I've seen a few around $30 on amazon.
Your no expert on explaining things that's for sure on and on and on and on can you not get straight to what we came to your video for,
Just test it so many unnecessary explanation let the test result speaks itself
You talk too much!
Get to the point in short time!!
