Overview

This is a five-nozzle 1/4″ quick-connect spray tip set in orifice size 7.5, covering 0°, 15°, 25°, and 40° high-pressure patterns plus a 65° chemical tip. Nozzle size has to match your machine's output: a size 7.5 orifice flows 5.03 GPM at 2000 PSI, 6.50 GPM at 3000 PSI, and 7.50 GPM at 4000 PSI, so this set is for higher-flow machines in that range. Swapping tips takes you from a pinpoint 0° blast for stubborn buildup to a wide 40° fan for rinsing, with the 65° tip for applying chemical. If you're not sure 7.5 is the right orifice for your pump, call us before ordering — a tip that's too small overpressurizes the machine.

Frequently asked questions

Size 7.5 is right if your machine's flow and pressure line up with the 7.5 orifice chart — about 6.50 GPM at 3000 PSI or 7.50 GPM at 4000 PSI. Check your machine's rated GPM and PSI against those figures; the 1/4″ quick-connect fitting itself fits any standard quick-connect lance or gun.

The set includes five 1/4″ quick-connect nozzles: 0°, 15°, 25°, and 40° high-pressure spray patterns, plus a 65° nozzle for chemical application. All five are size 7.5 orifice.

The 65° nozzle is the chemical tip — use it when applying detergent or cleaning chemicals rather than for high-pressure cleaning. The wide pattern spreads the solution evenly across the surface; switch back to a 15°–40° tip to rinse.

A nozzle orifice that's too small is bad for your machine — it restricts flow and pushes pressure beyond what the pump and unloader are set to handle. If you're not certain size 7.5 matches your unit's GPM and PSI, call APS for sizing guidance before ordering.
