It forms the sealed transition between the furnace's induced-draft outlet and the vent connector, directing combustion byproducts safely into the chimney. A cracked, rusted, or ill-fitting transition can leak flue gas — installing the correct OEM piece keeps venting sealed and code-compliant.\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eType:\u003c\/strong\u003e Chimney\/flue transition bottom\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial:\u003c\/strong\u003e Corrosion-resistant coated steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eApplication:\u003c\/strong\u003e 80% AFUE induced-draft furnace venting\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFit:\u003c\/strong\u003e Direct OEM replacement for AMH80403AXAA\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM Part No.:\u003c\/strong\u003e 0128F00006\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eOEM vs. Generic\u003c\/h3\u003e\u003cp\u003eThe \u003cstrong\u003eOEM 0128F00006\u003c\/strong\u003e matches the furnace's exact vent geometry and mounting points for a leak-free seal.
