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.\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eComponent: Chimney \/ flue vent collar\u003c\/li\u003e\n\u003cli\u003eOEM Part Number: 4053501S\u003c\/li\u003e\n\u003cli\u003eCompatible model: AMS80704BNAA\u003c\/li\u003e\n\u003cli\u003eEquipment type: Gas Furnace\u003c\/li\u003e\n\u003cli\u003eMaterial: Corrosion-resistant metal\u003c\/li\u003e\n\u003cli\u003eBrand: Goodman (fits Amana equivalents)\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eOEM vs. Generic\u003c\/h3\u003e\u003cp\u003eThe \u003cstrong\u003eOEM 4053501S\u003c\/strong\u003e is sized to the furnace's exact flue diameter and mounting pattern, so it seats flush and seals correctly.
