High pressure injection. If you like the way soap is applied at self serve car washes, this accessory is for you. It allows your pressure washer to apply soap the same way. The ST-64 injector is designed to introduce detergents into the water system upstream from the pump for high pressure application. An adjustment screw sets the orifice to the flow of your pump. The “on-off” plunger is then used to control the injection.

When using this injector, the operator should consider the types of chemicals used. Pump damage can occur if acids or other harsh chemicals are used. Easy to install, use, and maintain.
