Nozzle Size Selection Chart

Determine the nozzle size by the pressure washer’s GPM @ PSI (gallons per minute @ a specific pounds per square inch). If the nozzle size is too small, your equipment can be damaged. If the nozzle size is to large, cleaning ability is compromised. Nozzle fan degree does not effect nozzle size selection.
