Ideal for professional use, this Gilmour water spray gun has an all-zinc construction for durability and lasting performance. With its crush-proof build, the water gun resists up to 5,000 pounds of pressure to prevent damage to the coupling and body. It can handle 125 PSI to withstand high water pressure, making it great for on-the-job projects. The front tip is adjustable to regulate spray from a light rinse to a powerful jet. The thumb-control system lets you operate the spray gun with just one touch for comfort and easy operation.
