Lochinvar & A.O. Smith 100094965 Gasket

The Lochinvar & A.O. Smith 100094965 Main Gasket Kit is a critical OEM replacement component engineered for high-efficiency boiler and water heater maintenance. Specifically designed for units manufactured prior to serial number D14, this kit ensures a high-integrity seal between combustion components to maintain thermal efficiency and prevent hazardous gas or fluid leakage. This manifold gasket kit is a direct replacement for legacy part number GKT30023 and features a high-density, temperature-resistant material construction capable of withstanding the intense thermal cycling typical of commercial and residential hydronic systems.

For service technicians, using this genuine Lochinvar 100094965 gasket is vital for restoring the pressurized integrity of the heat exchanger assembly. The kit includes the necessary grey 5-hole gasket required for a flush, leak-proof fit. Inconsistent combustion or cooling cycles often stem from compromised seals in older standard gas boilers; replacing these worn components with OEM boiler parts prevents energy loss and protects internal hardware from moisture-driven corrosion. Always verify that your unit's serial number precedes the D14 cutoff to ensure precise mechanical compatibility.

• OEM Precision: Guaranteed 100% mechanical compatibility with Lochinvar and A.O. Smith boiler parts produced before serial D14.
• Thermal Stability: Heavy-duty material maintains sealing properties under high-temperature HVAC equipment operating conditions.
• Pressure Regulation: Facilitates proper internal pressure and prevents fluid interchange, reducing strain on the combustion blower.
• Extended Service Life: Prevents air infiltration and water leaks that cause chronic component failure in water heating systems.

Is the 100094965 compatible with all Lochinvar boilers?
No, this specific main gasket kit is only compatible with systems produced prior to serial number D14. For units manufactured after this date, a different part number is required to match the updated manifold configurations.

Does this kit replace the GKT30023?
Yes, the Lochinvar 100094965 is the current manufacturer-sanctioned replacement for the older GKT30023 part number.

What are the physical dimensions of this gasket?
The gasket features a 5-hole mounting pattern and is historically provided in a grey composite material designed for standard industrial and residential boiler housing fits.
