Lochinvar & A.O. Smith 100208101 Blower Gasket

The Lochinvar 100208101 Blower Gasket is a critical sealing component engineered for high-efficiency condensing boilers and water heaters. Designed to maintain the airtight integrity of the combustion assembly, this high-temperature gasket prevents flue gas leakage and ensures proper static pressure within the blower housing. This OEM part is a direct replacement for GKT2436 and GKT2436K, offering exact dimensional fitment for Lochinvar Knight and A.O. Smith Cyclone series units. Constructed from durable, heat-resistant materials, it withstands the thermal cycling common in modulating condensing boilers. When performing preventative maintenance or replacing a blower motor, replacing this gasket is necessary to ensure combustion efficiency and prevent CO leaks. Technical professionals prefer the 100208101 for its resilience against degradation from acidic condensate and pressurized combustion air, making it a staple for HVAC service kits and boiler repair applications across residential and commercial heating systems.

• Precision Fitment: Cross-referenced as a direct substitute for GKT2436K, ensuring a perfect seal without field modifications.
• High-Temperature Durability: Rated for the intense heat produced in Lochinvar burner assemblies, preventing premature failure.
• System Safety: Crucial for maintaining the air-fuel ratio by preventing unmetered air from entering the combustion chamber.
• OEM Reliability: Built to the original A.O. Smith specifications for long-term performance in high-demand environments.
