The Suttner Chemical Injector 999000019 is a precision-engineered ST-64 upstream chemical injector, designed for flow rates between 1.5 and 4.0 GPM. Ideal for low-flow pressure washing systems, this injector introduces detergents or chemicals before the pump, offering safe chemical application without exposing the high-pressure components to aggressive agents.
Constructed for durability and ease of use, this unit features 3/4\\” Female Garden Hose (FGH) inlet and 3/4\\” Male Garden Hose (MGH) outlet connections, making it compatible with residential and commercial setups that use garden hose fittings. The ST-64 series is known for consistent chemical draw and smooth operation across variable flow environments.
