Product Details

The Lennox 25W73 is a genuine OEM flue gasket designed for use in Lennox gas furnaces. This critical sealing component creates an airtight seal between the flue pipe and flue box, preventing combustion gases from escaping into living spaces while ensuring proper venting to the outside.

Key Features:

  • Genuine Lennox OEM part number 25W73 (100742-03)
  • Creates secure seal between flue pipe and flue box assembly
  • Prevents dangerous combustion gas leaks including carbon monoxide
  • Maintains heating efficiency and reduces energy waste
  • Heat-resistant construction designed for high-temperature applications

A worn or damaged flue gasket can compromise furnace efficiency, increase energy costs, and create potential safety hazards. Regular replacement of this gasket ensures optimal performance and safe operation of your Lennox heating system.
