Pressure Washer Nozzle Set Size 3.7

Overview

This is a five-piece Size 3.7 pressure washer nozzle set with 1/4″ quick-connect fittings. It includes 0°, 15°, 25°, and 40° high-pressure tips plus a 65° soap/chemical nozzle, so you can switch spray patterns for stripping, cleaning, rinsing, and applying detergent. The 3.7 orifice size is rated across a wide pressure range — 0.38 GPM at 40 PSI up to 4.19 GPM at 5000 PSI — so the tip you run depends on your machine's flow and the PSI you want to hit. Correct tip sizing matters: too small an orifice restricts flow and spikes pressure. Call for sizing help if you're unsure.
