This listing is for a single nozzle.
The best way to get the most out of your pressure washer is to leave the unloader valve completely open and control the pressure output using a different sized nozzle.
The Kranzle K1122TST is rated to at 2.1 Gallons Per Minute(GPM) Output. This 4.0 sized nozzle at 2.1 GPM gives us 1100PSI output, which is my preferred washer pressure.
This nozzle emits a 40 degree spray pattern. I've tried other patterns, but this one works the best for washing.
