The genuine OEM Goodman 10254303 Rubber Coupling is an exact-fit vibration-dampening seal for the Amana/Goodman AMV91155DXAB gas furnace. This flexible coupling connects and isolates moving components — commonly the inducer/drain and pressure-sensing assemblies — sealing the connection while absorbing motor vibration to keep the furnace running quietly and leak-free.
Off-brand couplings often use lower-grade rubber that hardens and cracks under repeated heating cycles, leading to air leaks that trip pressure switches or cause condensate drips. The genuine OEM 10254303 is molded to Goodman's exact durometer and dimensions for a lasting, factory-tight fit.
Easy (1/5) — Slip-on replacement; typically hand-fit or secured with a light clamp. Disconnect power before servicing and inspect the mating surfaces for debris. Confirm a snug, leak-free seat before restoring power.
