Lochinvar & A.O. Smith 100076307 O-Ring
For veteran technicians servicing high-efficiency systems, the Lochinvar & A.O. Smith 100076307 O-Ring is a critical OEM replacement part designed to maintain air-tight and fluid-tight seals in demanding thermal environments. This specific O-ring FKM (Fluorocarbon) component is engineered to handle the high-heat cycles common in condensing boilers and tankless water heaters, offering superior resistance to chemical degradation and oil-based fluids compared to standard nitrile or EPDM gaskets. When performing a heat exchanger service or HVAC repair, using this genuine factory part ensures a precise durometer match and geometric fit, preventing the nuisance leaks and pressure drops that lead to system downtime. As an HVAC technician, you know that FPM/FKM material provides the oxidative stability required for long-term reliability in specialized combustion environments. Integrating this A.O. Smith repair part during your seasonal maintenance or boiler manifold overhaul guarantees professional-grade performance and restores factory-spec integrity to the unit’s sealing surfaces.
Key Benefits:- Extreme Thermal Resistance: High-performance FKM fluoroelastomer maintains mechanical properties in temperatures exceeding 400°F (204°C).
- Chemical Inertness: Resistant to mineral oils, aggressive fuels, and combustion byproducts, ensuring the sealing gasket does not swell or degrade.
- Precision Geometry: Designed as a direct Lochinvar 100076307 equivalent to ensure a perfect seat in O-ring grooves without over-compression.
- Low Compression Set: Excellent "memory" characteristics prevent the sealing ring from hardening or flattening over time.
- Is this O-ring compatible with both Lochinvar and A.O. Smith units? Yes, this is a cross-branded OEM part used in various residential and commercial heating platforms from both manufacturers.
- Can I use a standard silicone O-ring instead of FKM? No. Silicone lacks the chemical resistance to petroleum-based lubricants and combustion additives often found in these HVAC applications.
- How do I ensure a proper seal during installation? Always inspect the mating surfaces for pitting and use a compatible thin film of lubricant if specified by the service manual.
