OVERVIEW
Designed to replace the black soap nozzle on pressure washers that use a factory chemical injector. The A-40 Airless Foam Wand quick connects to a pressure
washer gun and injects atmospheric air into the chemical solution to greatly increase volume and coverage ability. This stainless steel unit will create and project wet,
clinging foam on to surfaces up close or at a distance.
