Find the correct pressure washer nozzle orifice size for your machine. Enter your washer's rated flow rate and pressure—both are printed on the unit's label or listed in the owner's manual.
- GPM: gallons per minute, your machine's flow rate (typically 1.5–5 GPM for residential and professional units)
- PSI: pounds per square inch, your operating pressure (typically 1500–4000 PSI)
The result is the nozzle orifice size. Look for this number stamped on the nozzle tip or use it to cross-reference a nozzle size chart. A larger number means more flow; a smaller number means higher focused pressure.
