Stainless Steel TMT Inline Flow Switch for High-Pressure Systems | Summary
The General Pump 3/8" TMT Inline Flow Switch is a stainless steel inline flow switch featuring advanced Tri-Magnet Technology for ultra-reliable activation and durability. Designed for commercial pressure washing systems, this unit activates at just 1.5 GPM and can handle up to 12 GPM flow and 5000 PSI of pressure.
Built for performance and flexibility, this switch supports mounting in any position—no need to orient vertically. It’s especially well-suited for burner control or system automation in both cold and hot water applications.
Tri-Magnet 12 GPM Flow Switch with Stainless Steel Construction | Features
-
Tri-Magnet Technology – Uses a stainless steel shuttle and neodymium magnets for long-term reliability—no reed switches to fail.
-
Low Activation Threshold – Activates with as little as 1.5 GPM, ideal for lower flow burner setups or soft wash triggers.
-
Stainless Steel Body – Resists corrosion, pressure, and temperature extremes better than brass or plastic-bodied switches.
-
Compact Inline Design – Mounts easily into tight plumbing runs and functions in any orientation.
-
Minimal Pressure Drop – Optimized for unrestricted flow up to 12 GPM with low resistance.
-
Safe for Hot Water Systems – Rated for up to 180°F and 250V AC electrical systems.
