Designed for 2.2 – 5.5 GPM pressure washers, the Blue Mule Power Wash Spray-All is a machined stainless steel venturi system that quick connects to the trigger gun of a pressure washer. The system draws chemical concentrate from any container, dilutes the concentrate to the required ratio and applies the solution to any surface. These hose end systems can apply more aggressive chemicals since no chemical passes through the pressure washer pump, hose or trigger gun. Metering tips provide for up to 21 dilution ratios. For use wherever a pressure washer is needed, such as for cleaning buildings, vehicles, equipment or concrete.
