Lochinvar L100233643 Gasket

Product Description

The LOCHINVAR L100233643 is a replacement gasket designed to maintain a sealed connection in Lochinvar heating and hot water equipment. Gaskets of this type prevent fluid or combustion gas leakage at mating surfaces such as heat exchanger flanges, burner assemblies, or service access panels. Proper sealing is essential for safe and efficient system operation. Licensed plumbers, HVAC technicians, and boiler service professionals typically handle this type of replacement during scheduled maintenance or when an existing gasket shows signs of deterioration, compression set, or leakage.

This gasket is suited for use in residential and light commercial applications where Lochinvar heating or hot water equipment is installed. It is commonly replaced during annual service intervals, after heat exchanger inspection, or any time a sealing surface is disturbed during repair. Using the correct OEM-specified gasket ensures proper compression and a reliable seal when components are reassembled.
