Lochinvar & A.O. Smith 100233690 Gasket

The Lochinvar & A.O. Smith 100233690 Gasket is a critical OEM replacement part engineered for high-performance sealing in commercial boilers and hydronic heating systems. Specifically designed as a boiler flange gasket, this component ensures a gas-tight and fluid-tight seal between mating surfaces, preventing hazardous leaks and maintaining combustion efficiency. It is built to withstand the rigorous thermal cycling and high-pressure environments typical of Lochinvar Power-Fin (PBN) and Knight series units. This industrial HVAC gasket is vital for technicians performing routine boiler maintenance or heat exchanger service. Using genuine 100233690 Gasket components over generic alternatives ensures precise fitment, preventing costly callbacks due to seal failure. Its robust material composition resists degradation from chemical additives in the primary loop, securing long-term system integrity for hydronic applications. Whether you are servicing a water heater or a high-efficiency boiler, this flange gasket provides the exact tolerances required for professional-grade installs.

Key Benefits:

• Precision Engineering: Designed specifically for Lochinvar Power-Fin (PBN) and PBL series boilers to ensure airtight seals.
• High Temperature Resistance: Fabricated from durable materials that maintain structural integrity during extreme boiler heat cycles.
• OEM Standards: Eliminates the risk of improper fitment and gas leaks associated with non-genuine HVAC gaskets.
• System Efficiency: Prevents pressure loss and optimizes combustion by ensuring all flanged surfaces are properly coupled.

Common Questions:

• Which models are compatible with the 100233690 flange gasket? This gasket is primarily used in Lochinvar PBN and PBL models, including PBN0502 through PBN1302, as well as compatible A.O. Smith commercial units.
• Can I reuse an old boiler flange gasket? Standard industry practice for HVAC contractors is to replace gaskets every time the flange joint is broken to ensure a fresh, reliable seal.
• What does the 100233690 gasket seal? It provides a critical seal between the burner/blower assembly and the heat exchanger or on various flanged piping connections within the cabinet.
