Craftsman 317787GS Pressure Washer Chemical Injector Kit

The Craftsman 317787GS Chemical Injector Kit is a fluid delivery assembly designed to introduce cleaning solutions into the water stream of a compatible pressure washer. Its basic purpose is to regulate the mixing of detergent with pressurized water for cleaning work. The part operates by creating a pressure difference that draws chemical solution from a container through an inlet tube and into the flow of water before it reaches the spray wand. Mounted within the pressure washer plumbing system it assists with controlled detergent application, promotes consistent solution distribution and can improve cleaning efficiency on treated surfaces.
