The Goodman 10254303 Rubber Coupling is a genuine OEM sealing and vibration-isolation component for the GMH951155DXAF gas furnace and compatible Goodman/Amana models. This flexible rubber grommet/coupling forms an airtight, watertight connection on inducer, pressure-switch tubing, or condensate/drain interfaces while dampening blower and inducer vibration. A hardened, cracked, or missing coupling can cause air leaks that trip the pressure switch, condensate leaks, or transmitted noise and rattle.
OEM vs. Generic: Molded to the exact inner and outer diameters this furnace requires, the OEM coupling seats without leaks or forcing. Generic rubber pieces frequently mismatch the bore, leading to slow air leaks and intermittent pressure-switch faults that are frustrating to diagnose. For a reliable seal, use the OEM part.
Install Difficulty: Very Easy (1/5). Slips on by hand — no tools required in most positions. Ensure mating surfaces are clean and fully seated.
