Overview

This is a five-piece 1/4″ quick-connect spray nozzle set in orifice size 5.5, covering 0°, 15°, 25°, and 40° high-pressure patterns plus a 65° low-pressure chemical nozzle for applying soap. Size matters on nozzles: the 5.5 orifice is matched to your machine's flow and pressure — these tips flow 3.89 GPM at 2000 PSI, 4.76 GPM at 3000 PSI, and 5.50 GPM at 4000 PSI, so pick this set if your pump's GPM lines up with those numbers at your operating pressure. Running a tip that's too small chokes the pump and spikes pressure, so if you're not sure of your machine's rating, call us before you order — we've been sizing nozzles for over 25 years.

Frequently asked questions

Size 5.5 is the orifice size, which sets how much water passes through the tip at a given pressure — this set flows 3.89 GPM at 2000 PSI, 4.76 GPM at 3000 PSI, and 5.50 GPM at 4000 PSI. Match the orifice to your machine's GPM and PSI rating; a tip that's too small restricts flow and overpressures the pump. If you're unsure of your machine's rating, call us for sizing help.

Yes, these fit any lance or wand with a standard 1/4″ quick-connect coupler, which is the most common fitting on gas and commercial pressure washers. Just pull back the coupler collar, insert the nozzle, and release.

The 65° nozzle is the chemical nozzle — its larger opening drops the pressure so a downstream injector can draw detergent. The 0°, 15°, 25°, and 40° tips are high-pressure nozzles for blasting, stripping, general cleaning, and rinsing.

A too-small orifice is bad for the machine: it restricts flow, drives pressure above what the pump and unloader are set for, and forces the unloader into bypass more than it should. Always size the nozzle to your pump's GPM at your target PSI — call us if you need help choosing.
