Rheem-Ruud SP20732 Pressure Switch 323613-751 Durable Construction: Heavy-duty ASTM B584

Durable Construction: Heavy-duty ASTM B584 bronze body and alloy steel plated spring provide long-term structural integrity

While functionally similar to other exhaust airflow regulators

Its direct acting output ensures that an increase in sensed temperature results in a corresponding increase in branch pressure

3/4 HP Power Rating: Engineered for 208-230V single-phase applications

Rheem-Ruud SP20732 Pressure Switch 323613-751 Durable Construction: Heavy-duty ASTM B584The Rheem Ruud SP20732 Pressure Switch is a critical OEM replacement part designed for precision monitoring in HVAC induction systems and water heater gas valves. Engineered with a single pole single throw (SPST) electrical configuration, this component ensures the draft inducer motor generates sufficient negative pressure before allowing the ignition sequence to proceed. It functions as a primary safety interlock, preventing gas release if venting
