Lochinvar & A.O. Smith 100208087 Ignitor Gasket

The Lochinvar & A.O. Smith 100208087 Ignitor Gasket is a critical high-temperature seal required for maintaining the integrity of the combustion chamber in high-efficiency gas-fired systems. Professionally recognized as a direct replacement for the legacy GKT2012, this OEM ignitor gasket is engineered to withstand the extreme thermal cycling common in condensing boilers and water heaters. As a veteran technician knows, a compromised gasket leads to dangerous flue gas leakage and inconsistent flame rectification. This component provides the necessary airtight interface between the hot surface ignitor and the burner mounting plate, ensuring stable ignition across Lochinvar Knight and A.O. Smith residential water heater models. Utilizing high-grade, heat-resistant composite materials, the 100208087 (also cross-referenced as 100146427 and GKT2012K) ensures optimal combustion efficiency and system safety. When performing annual maintenance or replacing an ignitor, a fresh gas boiler gasket is non-negotiable to prevent air bypass and premature part failure.

Key Benefits

• Direct OEM Compatibility: Serves as the official successor to GKT2012, ensuring a precision fit without field modifications.
• Thermal Resilience: Constructed from advanced composite materials designed to endure high-velocity burner environments and prevent degradation.
• Flue Gas Containment: Establishes a secure combustion seal to prevent the escape of carbon monoxide and other combustion byproducts into the mechanical room.
• Versatile Application: Fits a broad range of Lochinvar and A.O. Smith heating systems, including RB, CB, and CH series boilers.

Common Questions

Is the 100208087 a direct replacement for my older GKT2012 gasket?
Yes, the 100208087 is technically identical to the GKT2012 and GKT2012K part numbers. It is the updated manufacturer-specified part for the same applications.

Which Lochinvar models use this specific ignitor gasket?
This gasket is commonly used in Lochinvar Knight (KBN, KBP), Copper-Fin, and Power-Fin units where the ignitor requires a dedicated mounting seal.

Can I reuse my existing gasket during an ignitor swap?
It is standard trade practice to replace the gasket during any service involving the removal of the ignitor. Reusing a compressed or heat-cycled gasket often results in combustion leaks and service recalls.
