Overview
The Suttner ST-601 is an inline, flow-through trigger gun rated for 4,000 PSI and up to 12.0 GPM, sold here as the direct replacement gun for all Whisper Wash surface cleaner models except the Hippo line. Its horizontal flow-through design mounts straight into the surface cleaner handle, and the German-engineered internals are built for hard commercial use: a forged brass housing, a unitized valve that swaps out in one piece for easy repair, and a stainless steel spring, needle, ball, and seat for chemical resistance. Heat- and chemical-resistant seals carry it to a 320°F max temperature, so it holds up on hot-water rigs and around cleaning chemicals. Inlet is 3/8" female NPT, outlet 1/4" female NPT.
