Lochinvar & A.O. Smith 100337717 Flange Gasket
When you are in the field performing standard maintenance or a full teardown on high-efficiency hydronic systems, the Lochinvar & A.O. Smith 100337717 Flange Gasket is a critical component for ensuring a gas-tight seal. This genuine OEM replacement part replaces the legacy part number 100133549 and is specifically engineered for precision fit within Lochinvar Power Fin (PF) series boilers, including the PF 250, PF 500, PF 750, and PF 1000 models. As a veteran technician knows, using a high-grade boiler flange gasket is the only way to prevent combustion leaks and maintain the precise air-to-fuel ratios required by modern A.O. Smith water heaters and commercial boilers. Constructed to withstand elevated temperatures and consistent pressure cycles, this gasket ensures the HVAC system sealing remains intact, protecting both the heat exchanger integrity and the overall combustion chamber performance. Whether you are servicing a residential unit or a large-scale commercial plant, this part is essential for preventing boiler leaks and passing final combustion testing.
Key Benefits:- Direct OEM Compatibility: Verified for use in Lochinvar Power Fin models (PF 250–1000) and compatible A.O. Smith water heaters.
- Superior Material Integrity: Designed to handle the high thermal demands of commercial heating systems without degrading or losing its seal.
- Perfect Fitment: Eliminates the risk of bypass or leakage common with generic, off-brand HVAC replacement gaskets.
- Critical Safety Component: Essential for maintaining a secure seal on flanged surfaces to ensure safe venting of combustion gases.
- Is this gasket a direct replacement for part 100133549? Yes, the 100337717 is the updated manufacturer-approved replacement for that legacy part number.
- Which Lochinvar models use this flange gasket? It is most commonly found on the Lochinvar Power Fin (PF) series, specifically the 250, 500, 750, and 1000 MBH units.
- Why is it necessary to replace the gasket during service? Standard boiler maintenance requires gasket replacement whenever the flange is disturbed to prevent vacuum leaks or exhaust gas discharge.
