The ST-1500W pressure washer trigger gun from Suttner can handle up to 12 gpm at a maximum pressure of 4000 psi. This German made spray gun has a standard 3/8 in female threaded inlet and 1/4 in female threaded outlet to accept a wide variety of pressure washer lances.

The ST-1500W features a pistol-grip design with weep operation. Weep pressure washer trigger guns allow a small amount of water to continue flowing at all times. The primary goal of this “weeping” action is to prevent guns and high pressure hoses from freezing in cold weather. These guns are very common in car wash, truck wash, and other wash bay environments in northern climates. Weep guns also reduce the initial pressure kick when the trigger is pulled.
