This sheet-metal transition directs combustion gases from the heat exchanger collar into the vent connector, forming a tight, properly sized draft path. Correct fit here is critical to safe venting — an ill-fitting substitute can cause flue-gas spillage, condensation, and premature corrosion.\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eOEM Part Number: 0128F00006\u003c\/li\u003e\n\u003cli\u003eCategory: Flue \/ Vent Transition\u003c\/li\u003e\n\u003cli\u003eCompatible Model: AMS80403AXAB (80% AFUE upflow furnace)\u003c\/li\u003e\n\u003cli\u003eMaterial: Corrosion-resistant coated steel\u003c\/li\u003e\n\u003cli\u003eFunction: Heat exchanger-to-vent draft transition\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eOEM vs. Generic\u003c\/h3\u003e\u003cp\u003eThe genuine Goodman part is stamped to exact factory dimensions so it seats against the collector box and vent collar without gaps.
