Pressure Washer Nozzle Selection Guide
Get The Right Nozzle For The Job!
Proper nozzle size selection is necessary for your pressure washer to operate at optimum performance.
If the nozzle size is too small, your pressure washer can be damaged. If the nozzle size is too large, cleaning ability is compromised. Correct nozzle size is calculated based on the pressure washer’s GPM @ PSI (gallons per minute at a specific pounds per square inch). Nozzle fan degree, or spray angle, does not effect the size of your nozzle orifice.
To find the correct nozzle size for your machine use our handy calculator, or download the selection chart below.
