Overview

The Simpson 7104228 is the genuine replacement soap (chemical) injector kit for pressure washers fitted with AAA and OEM Technologies pumps. The injector is the small check-valve fitting on the pump where the detergent hose attaches; when its ball or spring sticks or wears, the washer stops pulling soap. This kit restores the injector with new internal parts and a new brass barb fitting.
