Lochinvar & A.O. Smith 100233595 Gasket
The Lochinvar & A.O. Smith 100233595 Gasket is a critical 3" flue gasket engineered for high-efficiency condensing boilers and commercial water heaters. This OEM replacement part provides a high-temperature seal between the flue pipe and the heat exchanger, preventing the escape of combustion gases and acidic condensate. Designed for rugged service, this high-temperature boiler gasket maintains its structural integrity under extreme thermal cycling, ensuring the pressure vessel and venting system remain airtight.
For field technicians, the 100233595 is the standard specification for maintaining the combustion seal on a wide range of Lochinvar Knight (KBN), Armor (AWN), and Whisper-Step (WB) models, as well as A.O. Smith Cyclone (BFC) series units. Utilizing a precision-cut flue vent seal like this one is essential during annual teardowns or heat exchanger inspections to prevent CO leaks and ensure optimal blower pressure. This gasket is manufactured to withstand the corrosive environment of high-efficiency gas-fired appliances without degrading.
Key Benefits for the Contractor:- Precise 3-Inch Fit: Optimized for Lochinvar 3 inch flue assemblies to ensure a drop-in replacement without field modifications.
- Chemical Resistance: Designed to withstand the acidic nature of flue gas condensate in high-efficiency condensing water heaters.
- Thermal Stability: Heavy-duty material prevents compression set and leakage during high-fire operations.
- Safety Compliance: Meets manufacturer specifications for maintaining a sealed combustion environment in residential and commercial settings.
- When should this gasket be replaced? It is industry best practice to install a new 100233595 gasket whenever the flue collector or heat exchanger interface is opened for maintenance.
- Is this compatible with A.O. Smith units? Yes, this part is extensively used in A.O. Smith BFC, Innovo, and Twister II commercial models requiring a 3-inch discharge seal.
- Does it require additional sealant? No, this 3" flue gasket is designed to create a mechanical seal; using RTV or other adhesives can interfere with the fit.
