Lochinvar & A.O. Smith 100208754 Gasket Kit
Ensure a watertight seal on your hydraulic connections with the Lochinvar & A.O. Smith 100208754 Gasket Kit. This OEM 1-1/2 inch flange gasket set is engineered specifically for Lochinvar Energyrite pool heaters (models ER152 through ER402) and A.O. Smith commercial applications. As a veteran-grade pool heater gasket kit, it provides the critical thermal and chemical resistance required to maintain head assembly integrity under high-pressure cycles. Replacing these gaskets during routine teardowns prevents invasive leaks at the heat exchanger interface, protecting the heater body from corrosion and maintaining combustion efficiency.
Designed for professional installers, this 100208754 replacement part utilizes high-grade elastomeric materials that resist the degrading effects of chlorinated and brominated water. Whether you are performing a seasonal pool heater manifold repair or a full heat exchanger swap, using genuine Lochinvar heater parts ensures precise fitment to 1.5" flange specs, eliminating the risk of bypass or pressure loss common with generic seals. This kit is the standard for contractors maintaining AO Smith residential gas heaters and Energyrite systems where reliable sealing is non-negotiable.
Key Benefits for Technicians:
- OEM Fitment: Guaranteed compatibility with Lochinvar Energyrite ER152-ER402 and select A.O. Smith models.
- High-Temperature Rating: Engineered to withstand the thermal stressors found in gas-fired pool heating manifolds.
- Chemical Resistance: Specialized material prevents swelling or hardening when exposed to pool sanitizers.
- Pressure Integrity: Maintains a 1-1/2" flange seal to prevent heat loss and water damage to electronics.
- Simplified Maintenance: Direct replacement kit for part numbers 100208754 and old ERP-RP-20 standard listings.
Common Questions & Technical Support:
Is this kit compatible with ASME-rated models?
Yes, this gasket is the standard 1-1/2" flange seal used across all Energyrite ASME and non-ASME heat exchanger assemblies.
What causes these gaskets to fail prematurely?
Failure is typically caused by chemical imbalance (low pH) or over-tightening of the flange bolts, which can crush the internal seal geometry. Always check torque specs on the manifold.
Does this include the bolts and flanges?
This is the gasket kit only. If the flanges are corroded, a separate flange kit (100288537) containing bolts and gaskets may be required.
