This QC Soap Nozzle features an enlarged orifice designed to create the necessary pressure drop for activating downstream chemical injectors. Engineered for extended life and consistent performance, each nozzle is 100% tested for orifice accuracy and spray angle—ensuring reliable results with every use. Not using a chemical injector? It also serves as an effective low-pressure rinse option.

This Soap Nozzle has a black pressed head over a hardened brass body.
