Rheem-Ruud SP12541B Gas Valve

The Rheem-Ruud SP12541B Gas Valve is a professional-grade combination gas control engineered for precision fuel regulation in residential and light commercial gas water heaters. This OEM Rheem replacement part features a standard 3/4 inch NPT inlet and 3/4 inch NPT outlet, ensuring a secure, leak-resistant connection to the manifold and main gas supply lines. Built to handle low-pressure environments, it operates within a pressure range of 0.4" WC to 10" WC and includes an integrated 24V constant pilot system for reliable ignition sequences. As a veteran-preferred HVAC control valve, the SP12541B incorporates an essential safety shut-off mechanism that immediately terminates gas flow if the flame signal is lost. This Natural Gas valve is designed for high-efficiency operation, facilitating optimal combustion for consistent thermal output. Whether you are performing a routine swap or a critical system repair, this direct-fit gas valve provides the durable construction required to maintain factory-spec safety and performance in Rheem, Ruud, and ProTech water heating equipment.

• Direct OEM Compatibility: Precise fit for specific Rheem and Ruud gas water heaters, eliminating the need for field modifications.
• Enhanced Safety Logic: Features a high-reliability safety shut-off to prevent unburned gas accumulation.
• Durable Construction: Compact combination gas valve body (approx. 5-1/8" height) designed to withstand high-duty cycles.
• Precise Regulation: Maintains stable gas flow and pressure to optimize burner efficiency and reduce fuel waste.
• Standardized Fittings: Equipped with 3/4" NPT threads to match standard manifold configurations for faster installation.

• Does this valve support Propane conversion? This specific model is configured for Natural Gas; always verify the rating plate and use the correct gas-type specific components to avoid hazardous combustion.
• What causes a pilot outage on this valve? Common failure points include carbon buildup on the thermopile/electrode or a restricted pilot tube; ensure the 24VAC connection is stable before diagnosing a mechanical valve failure.
• How do I confirm the fitting size before teardown? The SP12541B utilizes 3/4-inch NPT inlet/outlet openings; verify your supply line and burner tube diameter to ensure compatibility with these larger 3/4" ports compared to 1/2" variants.
