The Goodman 4053501S is a genuine OEM chimney/flue vent collar engineered as a direct-fit replacement for the GMV80905CXBA 80% AFUE gas furnace. This collar seats the vent connection at the flue outlet, maintaining a tight, code-compliant seal between the furnace and the venting system so combustion byproducts are safely carried away. A worn, corroded, or missing collar can cause flue leaks, poor draft, and safety lockouts — replacing it restores proper venting performance.
This is the authentic Goodman OEM part, built to the exact flange dimensions and gauge of the original. Generic collars often vary slightly in diameter or bend, forcing gaps that leak flue gas. Choosing OEM guarantees a leak-free seal and preserves any remaining manufacturer warranty on your furnace.
Easy (1 of 5). Removes and reinstalls with a nut driver or screwdriver in about 15–20 minutes. Always shut off gas and power before servicing, and confirm proper draft after reassembly. If unsure, use a licensed HVAC technician.
