Description
The Lennox 25W72 is an OEM replacement gasket designed specifically for use with Lennox draft inducer assemblies. Engineered to deliver a precise, airtight seal between the draft inducer blower and the furnace heat exchanger or flue collar, this gasket helps maintain proper combustion airflow, prevents flue gas leakage, and supports safe, efficient furnace operation.
Product Overview
Draft inducer gaskets are a critical component in forced-air furnace systems. Over time, gaskets can deteriorate due to heat cycling, vibration, and age, leading to flue gas leaks, reduced combustion efficiency, and potential safety hazards. Replacing a worn or damaged gasket with the correct OEM part restores a proper seal and ensures the draft inducer operates as intended.
