The Adam's Pressure Washer Spray Gun attachment fits any pressure washer with a 3/8" quick disconnect fitting. The Adam's Foam Cannon uses a quick connect attached to the end to produce extreme foam. Most pressure washers have a typical wand style attachment, but that restricts you from getting into hard to reach areas. This product combines the proximity of your hand with the same power you're used to with your current pressure washer. Made from components in Italy and hand-assembled in the USA by MTM, this product features all stainless working components and a comfortable linear pull trigger.
