The orifice number is the gpm flow at 4000 psi. So if you have a 3.5gpm unit capable of 4000psi, the #3.5 is the smallest you should consider. You can go larger to a #4 or #4.5 to lower pressure and stress on the pump. In this case, the #4 will drop you to about 3000psi, and the #4.5 further drop you to about 2400psi and a #5 will drop further to about 2000psi. Remember, the pressure rating of your washer is the maximum. The correct way to lower pressure is to use a larger orifice, not mess with the unloader. More psi than needed just damages surfaces and makes a bigger mess.
Need some guidance. I already have some 2.5 & 3.5 for my Ryobi 1900 psi and 1.2gpm. Testing with my hand and cardboard, the 3.5 seems too harsh. Hurts the hand sooner than the 2.5. Solely used for washing cars, which is the best for that?
Seems like a reasonable assumption, the Nozzle Size Calculator might be able to confirm. But best to contact the manufacturer. www.mtmhydroparts.com/pages/nozzle-size-calculator
I purchased the 40 DEGREES 3.0 MTM ACQUALINE NOZZLE WITH BLUE GUARD but it doesn't say anywhere that its a 3.0. Is it engraved somewhere under the blue rubber guard? The traditional nozzles like in the video have it engraves on the side.
The nozzles are marked, near the tip of the nozzle versus the base. It can be difficult to see because the guard does get in the way. A flashlight may help in seeing the mark.
I have a Hart brand electric pressure...Rates itself as 2000 psi and 1.2 gpm...On your chart it shows a 1.7...So im assuming a 2.0 orifice would be right for me.?
The smaller the degree pattern the higher the applied pressure will be, so 25º and 15º tips will provide higher pressure with a good cleaning pattern versus the 0º nozzle which is like a laser. The tips themselves won't change the PSI or the flow of your machine. Make sure to pair your pressure washer with the appropriate orifice size when selecting nozzles (tips) to avoid damage to the pressure washer.
Perfect just what I wanted. Thanks
I've been using the green one for spraying off snowfoam / washing and only use the yellow / orange one for the door shuts / jams with no issues.

Director of Awesome! I love it.
Your videos are great! Thank you...
Mike it was very nice to meet you at the Ford Carlisle show 😀
Hello what size do you recommend for a husqvarna 2000 PSI Electric Pressure Washer 1.2GPM 2000psi calculator says 1.7 Nozzle size ?

If I am doing 1875 on PSI and 1.2 GPM, 2.0 way to go?
I have a 2700 psi gasoline pressure washer, can i use this pressure washer to wash my car with the white nozzle?
I looked at the yellow spray tip that came with the Hart washer...The number was 150165...Just wondering what size that would be.....1.65?

Can we have a demo please ;-)

Correct
@@PoweredbyVeloci Thank You..
I did my specs on the calculator site and it comes up at 1.9 what's that mean?
You would want to size your nozzles at 2.0

I did my spec calculation and it came up at 3.65. What size should i use
I need a tip for high pressure low water flow low gpm

It was my first time pressure washing my car and I used the 15 nozzle I hope I didn’t damage anything 😢
Pressure output (in bars) of your pressure washer also matters… domestic pressure washers don’t have much power
