What Size Nozzle Matches Your Machine?

Proper nozzle size is critical to get the best performance from your pressure washer. An undersized nozzle can create an overloading condition on the pump, even causing engine/motor or electrical issues. An oversized nozzle will result in lower pressure. Proper nozzle size is the best way to insure maximum value and performance from your equipment.

Don’t guess – if you know just a couple of specs you will get it right!

If you are trying to determine the correct nozzle size for the machine, and you know how many gallons per minute (GPM) it produces, as well as the rated pressure (PSI), use the Nozzle Size Calculator.

If you are trying to determine many gallons per minute (GPM) the machine produces, and you know the nozzle size and pressure that the machine produces, use the GPM Calculator.

If you are trying to determine how much pressure the machine should produce, and you know the correct nozzle and gallons per minute (GPM) the machine produces, use the PSI Calculator.

NOTE: Never go by a pump’s “maximum” pressure. Use the machine manufacturer’s specifications for your calculations.
