The Goodman 4053501S Chimney Collar is a genuine OEM flue-vent component engineered specifically for the Goodman GDS81155CXA gas furnace. This collar forms the sealed transition between the furnace vent outlet and the flue pipe, ensuring combustion byproducts are safely routed out of the home. A properly seated chimney collar is essential for maintaining draft, preventing flue-gas leakage, and passing combustion-safety inspection.
Manufactured to Goodman's exact factory tolerances, this part drops into place without modification and preserves the original venting geometry of your furnace. Aftermarket substitutes often require shimming or sealant workarounds that can compromise the vent seal.
Our OEM 4053501S guarantees a factory-precise fit and full compatibility with Goodman's venting specifications. Generic collars may vary in diameter and flange depth, risking leaks and failed inspections. For a safety-critical venting component, OEM is the recommended choice.
Rating: Easy (2/5). Removal and replacement typically takes 15–20 minutes with basic hand tools. As this is a flue-gas component, we strongly recommend a licensed HVAC technician confirm the vent seal and perform a combustion-safety check after installation.
