Choosing the Right Nozzle for Your Machine
The orifice size of the nozzle determines the operating pressure of your machine. As a rule of thumb, the smaller the orifice, the greater the restriction of water flowing through the machine. This cause the pressure to increase.
- Choosing a nozzle with too large of an orifice will reduce operating pressure.
- Choosing a nozzle with too small of an orifice will limit water flow and possibly create an excessive load on the machine.
Use the table below to select the properly sized nozzle for your machine. Determine the nozzle size by matching the operating pressure (PSI) of your machine to the gallons per minute (GPM).
