The collar connects the furnace draft-hood outlet to the vent pipe, ensuring combustion byproducts are drawn safely up the flue. A corroded, warped, or ill-fitting collar can leak flue gases and cause pressure-switch faults — using the correct factory part maintains a proper, code-compliant venting seal.\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003ePart Number: 4053501S\u003c\/li\u003e\n\u003cli\u003eFunction: Flue \/ vent connector collar\u003c\/li\u003e\n\u003cli\u003eApplication: 80% AFUE gas furnace venting\u003c\/li\u003e\n\u003cli\u003eFits: Goodman \/ Amana AMH80903BNAA and compatible models\u003c\/li\u003e\n\u003cli\u003eMaterial: Corrosion-resistant metal\u003c\/li\u003e\n\u003cli\u003eType: OEM factory replacement\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eOEM vs. Generic\u003c\/h3\u003e\u003cp\u003eBecause this part handles flue gases, exact fit is a safety matter.
