Description
The Lochinvar & A.O. Smith 100278051 Copper Tube Gasket is a sealing component used in boiler and water heating systems to create a tight, leak-resistant joint around copper tube connection. Installed at interface points between piping and equipment fittings the gasket maintains pressure integrity and prevents fluid leakage during circulation of heated water within the HVAC systems. It is commonly used in boiler assemblies where sealing of copper tube connection is required for safe and stable heating operation. Within the hydronic system, the gasket operate as a sealing interface that support pressure containment, connection stability, and consistent thermal system performance.
