Suttner ST-62 Adjustable Downstream Chemical Injector for pressure washers rated 2-8 GPM. Features an adjustable orifice that allows one injector to work across a range of flow rates, eliminating the need for multiple fixed-orifice injectors. Draws cleaning chemicals downstream of the pump when using a low-pressure (soap) nozzle. Specifications: - Flow Rate: 2-8 GPM (adjustable) - Max Pressure: 3600 PSI - Max Temperature: 194°F (90°C) - Inlet: 3/8" FPT (Female Pipe Thread) - Outlet: 3/8" FPT (Female Pipe Thread) - Chemical Port: 1/4" Hose Barb - Siphon Rate: Approximately 10:1 - Construction: Forged brass housing with stainless steel spring and ball Features: - Large control knob for easy flow adjustment - Single injector covers 2-8 GPM range (replaces multiple fixed injectors) - Forged brass construction for durability - Stainless steel internals resist corrosion - Compatible with ST-61 metering valve for precise chemical control (sold separately) How It Works: Install the ST-62 inline between the pump outlet and high-pressure hose. Adjusting the control knob changes the water flow restriction, creating a vacuum that draws chemical through the 1/4" barb when using a low-pressure nozzle (40° or larger).
