Pressure Washer Nozzle Selection Guide

Use the chart below to help with pressure washer spray tip / nozzle selection. You will need to know how many gallons per minute your pressure washer puts out as well as the maximum PSI rating.

Nozzle / Tip Size Selection Chart

Determine the proper nozzle size by the pressure washer’s GPM (Gallons Per Minute) at a specific PSI . If the nozzle size is too small, your equipment can be damaged . If the nozzle size is to large, your cleaning ability will be reduced. Please note that nozzle fan degree does not effect nozzle size selection.
