Bradford White 239-43241-00 Gasket

The Bradford White 239-43241-00 Gasket is a critical blower transition gasket engineered specifically for high-efficiency power-vented water heaters. Designed to provide an airtight seal between the combustion blower assembly and the exhaust transition, this component prevents toxic flue gas leakage and ensures proper static pressure within the combustion circuit. For contractors performing a water heater blower assembly replacement, replacing this gasket is standard practice to avoid pressure switch trip errors (EF or ER codes) caused by atmospheric leaks. This OEM gasket is fabricated from high-temperature elastomer materials capable of withstanding constant thermal cycling without losing compression set. It is compatible with Bradford White Defender Safety System models, including the RG2PV and MITW series. Utilizing a precision-fit gas water heater replacement part like this ensures the blower motor maintains the correct CFM output and venting velocity required for safe operation and code compliance on the job site.

• Ensures a vacuum-tight seal for power vent water heater repair to maintain proper pressure switch signaling.
• Manufactured from high-grade thermal interface material to resist degradation from exhaust heat and condensation.
• Direct OEM fitment for Bradford White 239-43241-00 eliminates the need for universal silicone sealants that can fail over time.
• Critical for maintaining the integrity of the flue exhaust system and preventing carbon monoxide leakage into the mechanical room.
• Reduces vibration-induced noise by providing a dampened interface between the blower housing and the tank transition.

When should the blower transition gasket be replaced?
This gasket should be replaced whenever the blower motor is pulled for inspection or replacement. Reusing a compressed gasket can lead to air bypass, causing the pressure switch to fail or preventing the burner from firing.

Will a leaking gasket cause a lockout code?
Yes, if the vent blower gasket fails, the pressure switch may not sense the required negative pressure, resulting in a system lockout. Replacing the 239-43241-00 is a primary step in troubleshooting venting issues.

Is this compatible with ultra-low NOx models?
While designed primarily for the RG2PV and MITW power vent series, always verify the specific blower housing part number against the manufacturer’s technical data sheet to ensure exact compatibility with ultra-low NOx configurations.
