Lochinvar & A.O. Smith 100288537 Flange
The Lochinvar & A.O. Smith 100288537 Flange is a critical OEM replacement part engineered for high-recovery heating systems and EnergyRite pool heaters. This 2-inch ER flange is designed to facilitate a robust, leak-free connection between the heat exchanger and the water supply piping. Built for commercial and industrial HVACR applications, the 100288537 ensures hydraulic integrity in systems where thermal expansion and high-flow velocities are constant. As a genuine Lochinvar water heater part, it maintains the precise geometry required for ASME-certified installations, preventing the turbulence and pressure drops often associated with secondary-market alternatives. Whether you are performing a routine heat exchanger service or a complete manifold overhaul, utilizing the correct water connection flange is essential for protecting the system's operational efficiency and avoiding premature failure at the union. This heavy-duty component is compatible with a wide range of Lochinvar and A.O. Smith units, providing the reliable sealing surface needed for professional-grade plumbing and mechanical contractor standards.
Key Benefits- Oversized 2" ER Bore: Specifically machined to accommodate high-flow rates in commercial water heaters and EnergyRite series heaters.
- Precise Gasket Seating: Engineered to provide a perfectly flat mating surface, reducing the risk of hairline leaks in high-pressure hydronic systems.
- OEM Compatibility: Guaranteed fit for Lochinvar and A.O. Smith models, ensuring the flange kit alignment matches existing factory specifications.
- Durable Construction: Manufactured from high-grade materials to withstand chronic thermal cycling without warping or degradation.
- Is this flange compatible with common pool heaters? Yes, this part is the standard 2" water connection flange specifically used in Lochinvar EnergyRite (ER) pool heater models.
- Does this include the entire flange kit? While often sold as a single 2" flange, it is designed to work as part of the 100288537 assembly which may require separate gaskets and bolts depending on your specific service requirements.
- Can I use this for both inlet and outlet connections? Yes, the 2" ER configuration is typical for both the input and output sides of the heat exchanger manifold on supported units.
