Its precise dimensions ensure proper draft, a leak-free seal, and correct alignment with the flue pipe or induced-draft assembly — a critical part of safe exhaust routing and reliable pressure-switch operation.\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eFunction: Flue\/vent transition adapter (bottom)\u003c\/li\u003e\n\u003cli\u003eMaterial: Formed metal venting component\u003c\/li\u003e\n\u003cli\u003eOEM Part Number: 0128F00006\u003c\/li\u003e\n\u003cli\u003eFits: Goodman WFM18140S5DNCB and compatible furnaces\u003c\/li\u003e\n\u003cli\u003eFactory-matched flange and outlet geometry\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eOEM vs. Generic\u003c\/h3\u003e\u003cp\u003eVenting transitions are model-specific stampings — flange bolt patterns, outlet diameter, and depth must match the collector box exactly. The OEM Goodman part guarantees a proper seal and correct draft. Generic or universal transitions frequently require modification and can introduce flue leaks or draft problems that trip the pressure switch. For a venting component, OEM fit is worth it.\u003c\/p\u003e\u003ch3\u003eInstallation Difficulty\u003c\/h3\u003e\u003cp\u003e\u003cstrong\u003eModerate (3\/5).\u003c\/strong\u003e Requires removing the existing transition, cleaning the mating surfaces, and re-sealing with high-temp silicone or gasket as originally applied.
