The Goodman 10254303 Rubber Coupling is a genuine OEM sealing and vibration-dampening component for the GKS90905DXAC furnace. It creates an airtight, flexible connection between rigid furnace components — commonly in the induced-draft venting or condensate path — absorbing vibration while preventing flue-gas and pressure leaks that would otherwise trip the pressure switch or reduce efficiency.
The OEM 10254303 is molded to the exact inside diameter and durometer needed for a leak-free seal on this furnace. Generic hardware-store couplings often differ in wall thickness or heat resistance, leading to slow leaks, pressure-switch faults, or premature cracking. For the low price, genuine OEM is the smart choice.
Easy (1 of 3). Power down the furnace, loosen the retaining clamps, slide off the old coupling, and seat the new one fully before re-tightening. Inspect mating surfaces for debris and confirm a snug, square fit so the seal holds pressure. No special tools required beyond a nut driver.
