TMT Brass Flow Switch for Pressure Washers and Soft Wash Systems | Summary
The General Pump 100904 Inline Flow Switch is engineered with Tri-Magnet Technology (TMT) and brass body construction to deliver long-lasting performance in pressure washer systems. This model provides on/off signal switching based on water flow without the need for pilot activation, simplifying your plumbing setup.
With activation as low as 0.5 GPM and 50 PSI, this switch is perfect for city water-fed soft wash systems, low-flow burners, or rinse triggers—yet still handles up to 12 GPM at 4000 PSI with minimal pressure drop.
