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.
Nozzle Fan Selection
Select the nozzle degree, or spray angle, based on your application. Standard nozzle degrees – 0°, 15°, 25°, and 40°. Using the wrong nozzle degree can damage the surface you are cleaning.
0° - Red:
15° - Yellow:

25° - Green:
Cutting nozzle- It delivers a concentrated stream that can gouge or cut. It can cut stubborn stains from concrete and other hard surfaces.
Chiseling nozzle- Working at a 45° angle, this nozzle works like a scraper, stripping paint, grease and grime from hard surfaces.
