Goodman 4053501S Chimney Collar

The 4053501S chimney collar is a genuine OEM flue/vent fitting for the Goodman AMS80704BNAA gas furnace. It forms the sealed transition between the furnace flue outlet and the vent pipe, ensuring proper draft and safe evacuation of combustion gases. A warped, rusted, or missing collar can cause flue-gas leakage and improper venting — a safety concern that should be corrected with an exact-fit OEM replacement.

Specifications

Component: Chimney / flue vent collar
OEM Part Number: 4053501S
Compatible model: AMS80704BNAA
Equipment type: Gas Furnace
Material: Corrosion-resistant metal
Brand: Goodman (fits Amana equivalents)

OEM vs. Generic

The OEM 4053501S is sized to the furnace's exact flue diameter and mounting pattern, so it seats flush and seals correctly. Generic collars may not match the outlet flange, risking gaps that leak flue gases. Because this part is combustion-safety related, OEM fit is strongly recommended.

Installation Difficulty

Rating: Easy. Typically fastens with a few sheet-metal screws at the flue outlet; 15–30 minutes. Verify a proper draft and inspect for leaks with the furnace running. Turn off power and gas before starting.
