Rheem-Ruud SP14339B Gas Valve

The Rheem-Ruud SP14339B Gas Valve is an OEM-grade Natural Gas Control Valve and Thermostat Assembly designed for high-capacity 75-gallon and select 50-plus gallon commercial and residential water heaters. Tailored for precision in demand-heavy environments, this water heater regulator maintains a factory-calibrated 5" Water Column (WC) pressure rating and features a standard 1/2" NPT inlet for professional-grade integration. As the direct engineering successor and replacement for the AP14339B and AP14339B-1, this unit integrates safety fail-safes and advanced temperature regulation into a compact housing to prevent burner short-cycling. The 2-1/4" shank length ensures seamless seating within the tank manifold, providing the reliable gas flow distribution required for Rheem RHGPRO75F and Ruud RUGPRO75F series. Contractors should verify the tank serial number to ensure exact HVAC part compatibility for these gas storage water heaters.
