Lochinvar & A.O. Smith 100327114 Volute Gasket
The Lochinvar & A.O. Smith 100327114 Volute Gasket is a critical OEM replacement part engineered to maintain the pressure seal between the pump volute and the motor housing. For field technicians servicing hydronic systems, this component is the direct replacement for 100133545, ensuring a precise fit without the need for field modifications. This boiler pump gasket is fabricated from high-grade elastomeric materials designed to withstand the thermal cycling and chemical treatments common in closed-loop heating applications. Using a genuine Lochinvar gasket is essential during routine maintenance or circulator pump repair to eliminate bypass leaks and prevent cavitation issues. Whether you are performing a seasonal teardown or responding to a failure, this 100327114 volute seal provides the structural integrity required for high-efficiency Lochinvar boilers and A.O. Smith units, ensuring the hydraulic assembly remains airtight and operates at peak system curve parameters.
Key Benefits- Precise OEM Fitment: Engineered as the direct replacement for 100133545, ensuring a drop-in installation for compatible Lochinvar boiler pumps.
- High-Temperature Durability: Specifically rated for the aggressive heating environments of hydronic systems to prevent compression set over time.
- Leak Prevention: Restores the airtight seal of the pump volute to maintain system pressure and protect surrounding electrical components from moisture.
- Broad Compatibility: Suitable for a variety of commercial and residential heating applications utilizing Lochinvar and A.O. Smith pump assemblies.
Is the 100327114 compatible with the older 100133545 part number?
Yes, the 100327114 is the manufacturer-designated direct replacement for part number 100133545. It maintains the same technical specifications and physical dimensions.
When should this volute gasket be replaced during service?
Technicians should replace the pump gasket every time the volute is separated from the motor housing or if there are any signs of weeping or calcification around the pump flange.
Does this gasket work for both Lochinvar and A.O. Smith units?
Yes, because these brands share specific hydraulic component designs, this OEM volute gasket is cross-compatible across several of their shared boiler and water heater pump platforms.
