Why Replace Your Door Gasket?

Over time, combustion door gaskets can harden, crack, or compress, breaking the airtight seal required for safe and efficient burner operation. Using a genuine OEM replacement like the 100208088 ensures the gasket meets the exact material and dimensional specifications of the original, helping to restore equipment performance and extend service life.
