Lochinvar L100287111 Heat Exchanger Top Plate Gasket

Product Description

The LOCHINVAR L100287111 is a heat exchanger top plate gasket designed to seal the top plate assembly on LOCHINVAR water heater units. This gasket maintains a pressure-tight, leak-free joint at the heat exchanger top plate interface, preventing combustion gas or water leakage that would compromise system efficiency and safety. It is a direct OEM-style replacement component installed by licensed plumbers or HVAC technicians during scheduled maintenance or heat exchanger service on LOCHINVAR water heater systems.

This gasket is specified for LOCHINVAR WH 56 through WH 86 water heater models. It is suited for residential and light commercial water heating applications where the heat exchanger top plate requires resealing due to gasket wear, compression set, or system inspection findings. Technicians typically encounter this part during annual maintenance cycles or when addressing water or flue gas leaks traced to the top plate joint.
