Lochinvar & A.O. Smith 100061501 Gasket

The Lochinvar & A.O. Smith 100061501 Volute Gasket is a critical OEM replacement part engineered specifically for Gen 2 commercial water heaters and high-efficiency boiler systems. This industrial-grade volute gasket provides a robust, high-temperature seal between the pump casing and the volute assembly, ensuring localized pressure containment within the circulating pump system. Designed to replace legacy part number 210742-000, this component is essential for preventing hazardous fluid leaks and maintaining the hydraulic integrity of your hot water plant. For the professional technician, this hydrostatic seal ensures that the pump operates at peak efficiency by eliminating bypass or external leakage. When performing boiler maintenance or a pump seal replacement, using a genuine 100061501 gasket is the only way to verify that the face-to-face dimensions and durometer ratings meet the original manufacturer specifications. Its durable elastomeric construction is formulated to withstand the thermal cycling typical of intensive commercial heating applications.

• Precise OEM Fit: Drop-in replacement for A.O. Smith 100061501 and Lochinvar 210742-000, ensuring zero-clearance sealing.
• High-Temperature Resilience: Specifically engineered to handle the constant thermal stress of commercial water heater volutes.
• Leak Prevention: Eliminates moisture escape at the volute-to-motor bracket interface to protect surrounding electrical components.
• System Efficiency: Maintains proper internal pressure within the circulating pump, preventing cavitation and performance loss.

• Is this gasket compatible with other pump brands? No, this is an OEM-specific part for AO Smith and Lochinvar Gen 2 units. Always verify your serial number before installation.
• Should I use pipe dope or sealant with this volute gasket? Most master technicians recommend installing the elastomeric gasket dry to prevent material degradation, provided the mating surfaces are cleaned of old debris.
• When should a volute gasket be replaced? It should be replaced every time the pump is pulled for service or if signs of "weeping" appear around the volute housing.
