This flexible coupling absorbs minor misalignment while providing a watertight, airtight seal between components. Rubber couplings harden and crack over time when exposed to heat and acidic condensate, so replacing this small part is a cheap way to stop leaks and prevent pressure-switch faults.\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eOEM Part Number: 10254303\u003c\/li\u003e\n\u003cli\u003ePart Type: Flexible rubber coupling \/ seal\u003c\/li\u003e\n\u003cli\u003eCompatibility: Goodman GMH951155DXAD and related GMH95 series furnaces\u003c\/li\u003e\n\u003cli\u003eMaterial: Heat- and corrosion-resistant rubber\u003c\/li\u003e\n\u003cli\u003eFunction: Seals and connects drain\/vent components\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eOEM vs. Generic\u003c\/h3\u003e\u003cp\u003eThe genuine \u003cstrong\u003eOEM Goodman\u003c\/strong\u003e coupling is molded to the exact inner diameter and wall thickness this furnace requires, ensuring a snug, leak-free fit. Generic couplings often run slightly over- or undersized, leading to weeping joints or clamps that won't seat properly. At this price point, the OEM part is the smart, reliable choice.\u003c\/p\u003e\u003ch3\u003eInstallation Difficulty\u003c\/h3\u003e\u003cp\u003e\u003cstrong\u003eEasy (1\/5)\u003c\/strong\u003e — Slip-fit with hose clamps; typically a few minutes with a nut driver.
