Lennox 52J98 Gasket

The Lennox 52J98 Gasket is a critical OEM replacement part engineered for high-efficiency furnace combustion blower assemblies. Also commonly identified by the Lennox 52J9801 part number, this high-temperature combustion air assembly gasket is used to eliminate air bypass and ensure a hermetic seal between the inducer motor and the heat exchanger collector box. Proper sealing is necessary to maintain the integrity of the combustion process, preventing the leakage of hazardous flue gases and protecting the HVAC system from efficiency loss due to static pressure drops.

Designed for professional-grade reliability, the Lennox 52J98 measures 5 inches by 5 inches with a 0.2-inch thickness, specifically profiled for Lennox gas furnaces and packaged unit RTUs. This component is compatible with a wide range of models, including the 90UGFA, G26Q3, and G26Q3-75 series. Using a precision-cut Lennox 52J98 Gasket-Combustion Blower Assembly allows technicians to restore equipment to factory specifications, ensuring optimal oxygen-to-fuel ratios and preventing premature blower motor failure caused by thermal exposure or vibratory wear.

• Precision Sealing: Engineered to provide a high-pressure contact seal, preventing flue gas discharge and secondary air infiltration.
• Thermal Resistance: Manufactured from robust, high-temperature materials capable of withstanding the extreme conditions within the combustion air assembly.
• Exact Compatibility: Direct fit for Lennox and Allied Air brands, including Armstrong and Ducane, ensuring 52J98 is identical to 52J9801.
• Operational Efficiency: Eliminates air leaks that can lead to pressure switch errors and increased energy consumption.
• Field Durability: Resists chemical degradation from combustion byproducts, extending the service life of the combustion blower interface.

Is the Lennox 52J98 gasket different from the 52J9801?
No, 52J98 is identical to 52J9801; they are the same Genuine OEM component used in various cataloging systems for Lennox Parts.

What happens if the combustion blower gasket fails?
A failed gasket can cause the furnace to leak carbon monoxide into the cabinet, trip the pressure switch, or allow heat to damage the inducer motor bearings.

Does this gasket fit 90% AFUE furnaces?
Yes, this combustion blower assembly gasket is frequently specified for Lennox 90UGFA and G26 series high-efficiency furnaces.
