Choosing the Right Nozzle Size

Nozzle size directly impacts flow and pressure balance. A #4.0 nozzle is typically suited for pressure washers producing approximately 3.5–4.0 GPM at higher PSI levels. Proper sizing ensures:

• Maximum cleaning efficiency

• Optimal pump performance

• Reduced strain on equipment

• Improved hose propulsion

⚠ Important: Always match nozzle size to your pressure washer’s GPM and PSI output to prevent overloading the pump.
