3/8" W-20SS Injector Kit W/ QDs

Model # VC-1200

Designed for 3.5–5.5 GPM pressure washers, the W-20SS quick-connect chemical injector attaches to a pressure washer outlet or installs in-line between hoses. This venturi unit draws and blends chemical concentrate into the water stream to create an accurately diluted solution. The solution then flows through the hose to the gun, where the user must connect a compatible A-20SS Airless Foam Wand or spray nozzle. Foam wand not included, see options.
