Description
The Lennox 25W73 Flue Gasket is a sealing part fitted between vent and flue connections in gas-fired heating equipment. It forms a tight barrier around the exhaust section to limit leakage of combustion gases and maintain proper vent passage conditions during operation. Commonly found in furnaces, boilers, and other HVAC systems, this gasket is placed between adjoining flue surfaces within the appliance vent assembly. Its purpose is to maintain a secure connection around the exhaust pathway while supporting proper airflow movement through the heating unit in residential and commercial applications.
