Pressure Washer Nozzle Set Size 4.5

Overview

This is a five-piece 1/4″ quick-connect pressure washer nozzle set in orifice size 4.5, covering 0°, 15°, 25°, and 40° high-pressure spray patterns plus a 65° low-pressure nozzle for applying chemical. A size 4.5 orifice flows 3.90 GPM at 3,000 PSI and 4.50 GPM at 4,000 PSI, so match this set to a machine whose pump output lands on that curve — running a tip that's too small for your pump builds excess pressure and is hard on the system. The tips snap into any standard 1/4″ quick-connect coupler on your lance. If you're not sure 4.5 is the right size for your GPM and PSI, call us and we'll size it for you.
