ST-601 Spray Gun, 12 GPM/4000 PSI

ST-601 Spray Gun, High-Flow Control for Rigs up to 12 GPM

Big-water machines need a trigger gun that can actually pass the flow. The ST-601 is rated for 12 GPM at 4000 PSI, which makes it a strong choice for hydro excavation work and large commercial pressure washers that would choke a standard gun.

Key Features

• 12 GPM flow rating: handles high-volume rigs without starving the nozzle.
• 4000 PSI rating: matched to most commercial cold water machines in its flow class.
• Trigger control at the gun: shut water off between passes to cut waste and keep the wand manageable.

Specs

Verify your machine's GPM and PSI before ordering so the gun's ratings cover your system with room to spare.

Pair it with a lance and fittings rated for high flow so the whole assembly keeps up.
