Nozzle Sizing ChartWater is an incredibly powerful force when delivered under pressure, with a low-pressure washer nozzle spraying at a wide angle safe for washing your car's finish, while high pressure, acute angle delivery could actually cut right through the steel! Important factors to consider when choosing the correct nozzle for a specific application are your equipment's PSI & GPM ratings, nozzle size and angle (fan) degree. This nozzle size chart allows you to easily select the correct nozzle size by cross-referencing your unit's GPM and PSI ratings to arrive at the correct standard nozzle size listed in the far left column. Our nozzles are color-coded to indicate angle degrees. When choosing a cutting nozzle size, choose a red tipped, 0° unit for best results. A water jet nozzle will typically be a green, 25° tip or, for washing vehicles, a white, 40° tip. |
