A.o. Smith 100338931 Cork Gasket

Product Description

The A.O. SMITH 100338931 is a cork gasket designed to provide a reliable seal in water heating equipment. Cork gaskets serve as compressible sealing elements, filling the interface between mating surfaces to prevent leaks of water or other fluids. This part is typically installed by plumbers or HVAC technicians during routine maintenance, repair, or component replacement on water heater assemblies. The cork material conforms to surface irregularities, helping maintain a consistent seal under normal operating conditions.

This gasket is suited for use in residential and light commercial water heating applications where a cork sealing element is specified. It is intended as a direct replacement part for A.O. SMITH water heater units that call for this gasket in their service documentation. Installers working on water heater repairs will find this part appropriate when the original gasket shows signs of compression set, cracking, or deterioration.
