Why Replace Your Collector Box Cover Gasket?
Over time, gaskets can crack, harden, or deteriorate due to repeated thermal cycling and exposure to combustion byproducts. A failed gasket can allow flue gases to escape the collector box, reducing system efficiency and potentially creating safety hazards. Replacing the gasket with a genuine Lennox OEM part restores the integrity of the seal and helps extend the service life of your equipment.
