Description

Why Replace Your Collector Box Gasket?
Over time, collector box gaskets can deteriorate due to repeated thermal cycling, moisture exposure, and age. A worn or cracked gasket may result in flue gas leakage, pressure switch faults, or reduced combustion efficiency. Replacing the gasket with a genuine Lennox part ensures the furnace operates safely and at peak performance.
