I know they make larger orifice tips which lower the pressure, but i can't find anything that lowers the pressure and allowed you to hook up a quick connect fitting to run a surface cleaner. I have a 3.5gpm pressure washer that is 4000psi. I'm looking to lower the pressure 600psi to run a surface cleaner.
