Suttner ST-1500H Open Spray Gun for Manual Start Pressure Washers, 3/8" FPT Inlet, 300°F

The Suttner ST-1500H is an open, flow-through spray gun built for manual start pressure washers and machines without an unloader valve. With no trigger to interrupt flow, the gun sprays whenever the machine is running, so the operator controls the job at the machine.

On long jobs like large flatwork, fleet washing, or commercial cleaning, an open gun cuts hand fatigue because there's no trigger to hold for hours. Its simple flow-through design has very few internal parts to wear out, which keeps maintenance easy and downtime low.

The ST-1500H is also a common choice for steam cleaners, where constant flow helps prevent overpressurization. Rental yards like it because a machine can't be left sitting in bypass, which protects the pump from overheating.
