The Goodman 0128F00006 Chimney Transition Bottom is a genuine OEM flue-vent component for the ACVC81005CXBD gas furnace and compatible models. This galvanized transition connects the furnace's vent outlet to the chimney or vent pipe, channeling combustion byproducts safely out of the home. A proper-fitting transition is critical for maintaining draft and preventing flue-gas spillage into the living space.
The genuine Goodman OEM transition is stamped to the exact dimensions of your furnace's vent collar, ensuring a leak-free, draft-correct fit. Generic or fabricated transitions risk gaps and misalignment that can compromise venting. For a flue-gas component, OEM fit is the safe choice.
Easy (1/5) — Sheet-metal screws and fit-up at the vent outlet. Ensure all seams are sealed with approved foil tape or sealant and verify proper draft after installation.
