Nozzle Size Calculator
To determine your nozzle size enter your pressure washer’s Gallons Per Minute (GPM) at the Pounds Per Square Inch (PSI) you would like to operate at.
If your result is higher than 10, round DOWN to the nearest available nozzle size.
Improperly sized nozzles can damage your pressure washer or result in compromised cleaning ability.

Pressure washing with a standard quick connect nozzle is great, but sometimes you just need a little more ‘punch.’ That’s when you want to take a look at our A+, Legacy, or Giant Turbo Laser Nozzles and RotoMax rotating nozzles!
Commonly referred to as Whirlybird Nozzles, these rotating nozzles are quite powerful and quickly reduce your pressure washing time. Each nozzle begins with a zero degree spray pattern, and spins the high pressure washer at a high RPM. The higher the RPM, the more aggressive cleaning you will receive.
We highly recommend the purchase of one of our Rotating Nozzle Filters for use with all of our rotating nozzles. These inline filters remove small particles of sand and debris commonly found in water sources and wells that can damage the internal components of these nozzles.
