Lennox Flue Gasket for Gas Furnaces

Lennox flue gaskets are OEM replacement seals for gas furnaces. They are also called flue box gaskets or flue collector gaskets. Each gasket makes a leak-tight seal between flue and venting components, such as the flue collector box and the inducer assembly. A good seal keeps combustion byproducts moving through the venting system and out of the furnace cabinet and living space.

Key Features:

• Genuine Lennox OEM replacement part, made to match the original equipment
• Seals the flue connection to help prevent combustion gas leaks
• Heat-resistant sealing material made for the thermal cycling in furnace operation
• Helps keep the pressure and draft the furnace needs to run as designed
• Drop-in replacement for gaskets that are worn, compressed, brittle or cracked

Furnace gaskets can harden and degrade over time from heat cycling, moisture and normal wear. Replace the gasket whenever you service the flue, collector box or inducer assembly. A fresh gasket helps the furnace run safely and efficiently. Installation should follow Lennox service instructions.
