Lochinvar & A.O. Smith 100338896 Gasket
The Lochinvar & A.O. Smith 100338896 Gasket is a critical OEM replacement part engineered for high-efficiency condensing boilers and water heaters. Constructed from high-grade EPDM (Ethylene Propylene Diene Monomer), this condensate trap gasket provides exceptional resistance to heat, weathering, and the acidic nature of HVAC condensate. It is vital for maintaining a gas-tight seal within the condensate management system, preventing hazardous flue gas leakage and moisture damage to the combustion chamber assembly. As a direct replacement for part 100228369, the 100338896 ensures precise dimensional compatibility with Lochinvar Knight and A.O. Smith Cyclone series units. For technicians performing annual maintenance or resolving pressure switch faults, replacing this EPDM seal is standard practice to ensure atmospheric integrity. Its robust chemical profile allows it to withstand the thermal cycling typical of commercial and residential hydronic applications without degrading or losing its compression set.
Key Benefits- EPDM Construction: Superior resistance to acidic condensate and high-temperature fluctuations common in condensing appliances.
- Precision Fit: Designed specifically for the condensate trap assembly to eliminate bypass and ensure proper drainage.
- Direct OEM Substitute: Serves as the factory-authorized replacement for legacy part number 100228369.
- System Integrity: Prevents the escape of combustion byproducts, maintaining safe and efficient HVACR boiler operation.
Is the 100338896 gasket compatible with both Lochinvar and A.O. Smith units?
Yes, this is a shared OEM part used across both brands, specifically within their high-efficiency condensing boiler and water heater lines that utilize a standardized condensate trap.
When should the condensate trap gasket be replaced?
Technicians should inspect the EPDM seal during every annual service. If the gasket shows signs of hardening, cracking, or if there is visible evidence of leaking around the trap housing, immediate replacement is required.
Does this part include the entire condensate trap?
No, the 100338896 is the replacement gasket only. If the plastic trap body itself is cracked or fouled, the complete trap assembly must be ordered separately.
