Lochinvar & A.O. Smith 100208756 Gasket

The Lochinvar & A.O. Smith 100208756 Gasket is a critical heat shield gasket designed for high-temperature sealing in commercial boilers and ASME EnergyRite pool heaters. This OEM component serves as a direct replacement for GKT2418 and GKT2418K, ensuring a precision fit within the combustion chamber and burner assembly. Fabricated from durable, heat-resistant materials, this replacement boiler gasket prevents flue gas leakage and maintains the thermal integrity of the heat exchanger. For technicians performing annual maintenance or a combustion chamber repair, using the correct OEM HVAC part is essential to prevent CO leaks and maintain system efficiency. This gasket is lightweight at 0.07 lbs, yet it is engineered to withstand the rigorous heating cycles of Lochinvar Power-fin and Armor water heater units. Always inspect the surrounding insulation and sealing compounds during installation to ensure a gas-tight seal and optimal condensing boiler performance.

• Direct OEM Compatibility: Engineered for a perfect fit, replacing part numbers GKT2418 and GKT2418K without structural modification.
• High-Temperature Resilience: Specifically rated as a heat shield gasket to withstand extreme internal combustion environment temperatures.
• System Safety: Prevents bypass of combustion gases, protecting external components and ensuring HVAC safety compliance.
• Broad Application: Compatible with ALL ASME EnergyRite pool heaters and various Lochinvar commercial series boilers.

Is 100208756 interchangeable with GKT2418?
Yes, 100208756 is the current manufacturer part number and is technically identical to the older GKT2418 and GKT2418K versions.

What happens if the heat shield gasket fails?
A compromised heat shield gasket can lead to scorched internal wiring, burner manifold damage, and dangerous flue gas leakage into the mechanical room.

Do I need additional sealants for installation?
While the 100208756 gasket provides the primary seal, technicians often use high-temp silicone RTV on cut surfaces or seams as specified in Lochinvar service manuals.
