(DISCONTINUED BY MANUFACTURER)

SEE REPLACEMENT PART: 3029P

The Tecmark 3925 Universal Pressure Switch W/Brass Fittings is a heater safety/control component used to verify proper water pressure or flow conditions before heater operation. Pressure switches help protect heater equipment by preventing firing when flow is not adequate, and the electrical rating, switch action, connection type, and fitting style all matter when selecting a replacement. This part should be matched to the existing Tecmark switch, heater wiring, and pressure connection rather than chosen by appearance alone. Confirm the specification details (as listed in the title) and part number 3925 before installation.
