Lochinvar & A.O. Smith 100208760 Gasket

Maintain the combustion integrity of your high-efficiency systems with the Lochinvar & A.O. Smith 100208760 Gasket. Engineering specifically for the Venturi gas valve assembly, this OEM replacement part is essential for technicians performing routine maintenance or emergency repairs on Lochinvar Armor series and A.O. Smith water heaters. It replaces outdated part numbers including GKT2443, GKT2443K, and 100146546, ensuring a precise, airtight seal between the venturi and the gas valve. By preventing critical air or gas bypass, this venturi gasket sustains uniform ignition and stable burner operation under varying load conditions. Manufactured to withstand the thermal stressors found in modern gas-fired HVAC systems, the 100208760 is a vital component for ensuring the long-term reliability and fuel-to-air ratio accuracy in residential and light commercial boiler systems.

• Precision Seal: Engineered specifically for the venturi gas valve interface to eliminate gas leaks and ensure 100% combustion stability.
• Extensive Compatibility: Fits various high-efficiency models including AWN151PM, AWN200PM, AWN201PM, and Armor Wall Mount (WA 125 thru 20) series.
• Direct OEM Replacement: Ensures exact dimensional matching for the 100208760 part number, avoiding the fitment issues common with generic aftermarket seals.
• System Efficiency: Maintains proper pressure and airflow through the venturi, preventing irregular burner firing and optimizing overall system performance.

When should the venturi gasket be replaced?
Technicians should inspect the gasket during any gas train service or if there are signs of combustion instability. It is best practice to replace the gasket whenever the venturi is detached from the gas valve to prevent future leaks.

Will this part work with my specific Lochinvar model?
