Bradford White 239-43371-00 Gasket
The Bradford White 239-43371-00 Gasket is a critical combustion chamber component designed specifically for flame sensor mounting on Defender Safety System water heaters. This high-temperature specialized gasket ensures a hermetic seal against the inner door glass, preventing secondary air infiltration that can disrupt the burner's flame signal and lead to nuisance lockouts. Engineered for use in atmospheric vent gas water heaters, this OEM replacement part maintains the integrity of the Flammable Vapor Ignition Resistant (FVIR) system. When performing a flame sensor replacement, contractors must ensure this gasket is pliable and intact to prevent carbon monoxide leakage or burner interference. This component is compatible with a wide range of RG2, MI, and M-I-MS models, providing a precise fit for the flame sensor probe assembly during standard maintenance or thermocouple upgrades.
Key Benefits:- Maintains Combustion Seal: Prevents bypass air from entering the combustion chamber to ensure stable flame rectification.
- High-Temperature Resistance: Formulated to withstand the intense thermal cycling of the sealed combustion chamber.
- OEM Fitment: Eliminates the need for field modifications, ensuring Bradford White 239-43371-00 compatibility with factory specifications.
- System Safety: Essential for maintaining the FVIR safety standards required for residential gas water heaters.
When should the Bradford White 239-43371-00 gasket be replaced?
Inspect the gasket during every burner assembly service. If the material shows signs of brittleness, cracking, or compression set, it must be replaced to prevent air leaks.
Does this part work with all Bradford White atmospheric models?
It is specific to units utilizing the Defender Safety System. Always verify the model and serial number to ensure this gasket matches your specific burner door configuration.
Can I use high-temp silicone instead of this gasket?
No. Using RTV or silicone can off-gas and coat the flame sensor, leading to premature failure. Only the genuine OEM gasket should be used to seal the sensor interface.
