Lochinvar & A.O. Smith 100109686 Gasket
The Lochinvar & A.O. Smith 100109686 Cleanout Gasket is a critical OEM replacement part engineered for high-recovery commercial and residential water heaters. As a veteran-grade HVAC sealing component, this gasket is the direct updated version of the legacy 9004099015 and 9004099215 part numbers, ensuring a precise 4-1/8" x 5-1/16" profile for a leak-proof fit. Designed to withstand the thermal expansion and high-pressure environments typical of Lochinvar and A.O. Smith tanks, this 1/8-inch thick gasket prevents atmospheric contamination and water seepage at the cleanout interface. When performing a water heater tank flush or sediment removal, replacing the cleanout plug gasket is standard protocol to maintain system integrity. Utilizing genuine AO Smith parts like the 100109686 ensures that the high-temperature seal remains intact, avoiding the premature degradation often seen with generic alternatives. This replacement heating part is essential for contractors maintaining commercial gas water heaters where consistent uptime is non-negotiable.
Key Benefits
- Direct OEM Compatibility: Specifically engineered to replace discontinued part numbers 9004099015, 9004099215, and 99038 without any modifications.
- High-Temperature Resistance: Fabricated from durable, flexible materials designed to maintain a hermetic seal under extreme thermal cycles.
- Precision Dimensions: Standardized at 4-1/8" x 5-1/16" x 1/8" to ensure an exact fit for standard cleanout plugs on major Lochinvar and A.O. Smith models.
- Leak Prevention: Eliminates moisture bypass and external corrosion at the tank's access point, preserving the structural integrity of the water heater tank.
Common Questions
Is the 100109686 compatible with older 9004099015 gaskets?
Yes, the 100109686 is the official updated replacement for the 9004099015 and is fully backward compatible with all units originally requiring that part number.
When should an HVAC technician replace the cleanout gasket?
It is standard practice to install a new gasket every time the cleanout plug is removed for tank descaling or inspection, as the material compresses over time and may not reseal properly once disturbed.
Will this gasket fit other brands besides Lochinvar and A.O. Smith?
While primarily designed for these brands, this mechanical seal may fit other commercial tanks; however, always verify the 4-1/8" x 5-1/16" dimensions and OEM part number before installation.
