When applying harsh pressure washing chemicals and acids with the use of a downstream detergent injector, we highly recommend our Interpump variable pressure dual lance wands. These industrial grade wands are zinc-plated for chemical resistance, and the brass and stainless steel valve uses viton seals, for high resistance to harsh power washing detergents. Simply turn the side handle to adjust pressure washer operating pressure. Interpump dual lance wands can be used at pressures up to 3000 PSI and 10 GPM with a maximum temperature rating of 220 degrees F.
