Sorry about that Innocent Bystander I hadnāt seen this site is USA based. Iām actually the Website Administrator for Southern Tank Services in the UK I certainly didnāt intend to spam. The information isnāt entirely useless as Iād still recommend something of that ilk and we do supply some nozzle pieces which we likely could still post to the US if they turned out cheaper.
I guess thatāll depend on how well Brexit turns out I guess! haha
Anyway, Sorry again

No worries. The owner of this forum is a vendor and we try to support him. Good luck with Brexit across the pond. We have our on trouble here with the orange haired wonder in the oval office 
Hey trying to figure out what nozzles I need for my new setupā¦ I have a 8gpm 3500 psi running a 19ā 4 nozzle bar classic ā¦ what nozzles should I run so I get around 2000 psi on the sc? The 4 bar came with 2502 nozzle which that gives me 2gpm at each nozzle ā¦ what I donāt know what kinda pressure I will have , havenāt use it yet ā¦

That website has a chart and a calculator.
So I should be running 4 25025ā¦ I run 2 of those tips now on my 5.6 gpm machine
Never mind I found some for info on another tread
Ok so just to be 110% clear. A 4gpm
Machine would need 2525 nozzles to obtain 2500 psi on a surface cleaner. With 200ā of hose technically you would be putting out somewhere around 2200 psi??
A 4gpm running a 2-nozzle SC would need 25025 nozzles, not 2525. 2525 would only produce about 26psi

Im a bit lost here. I keep hearing 25025 on a 4 gpm 2 nozel SC will put out 2500 psi. I have 25025s in my SC and I am reading 3300 on the gage, and 3000 on the chart, and its etching concrete that is not new. So I was going to go with 25050. When i consulted a chart designed for surface cleaners, it intersected 4gpm, 2500 psi, with 5.0
Remember you have to split that 5.0 in two for the surface cleaner. Is the gauge showing 3300 mounted on the SC gun when operating it?
You can certainly try 2503ās, I played around with nozzle sizes when I had my 4gpm.
2505 would give you 677 psi at 4gpm.
2503 would give you 1777 at 4gpm.
This is very easy. Divide your gpm by the number of tips. So youāre looking at 2gpm on the chart.
Hereās a user friendly calculator:

3300 on SC gun
Also, if youāre etching concrete, itās more probable that one of your installed 25025 tips is clogged with a bit of sand or trash. That can cause higher nozzle pressures and all sorts of issues. Remove/replace

That, or it may be turned to the incorrect orientationā¦hadnāt thought of that either.

They are l8ned up perfect with the bar, no clogging at all. Im gonna throw the 25030 in tomorrow and see where that leads.
