The Goodman 10254303 is a genuine OEM rubber coupling for Amana/Goodman AMH950703BXAD 95% AFUE gas furnaces. This flexible coupling joins vent, intake, or condensate components and forms an airtight, water-tight seal at the connection point. In a high-efficiency condensing furnace, sealed connections are essential — a degraded coupling can allow condensate leaks or venting/pressure faults that trip the pressure switch and prevent ignition.
Generic rubber couplings often use inferior compounds that harden, shrink, or crack under the heat and acidic condensate found in condensing furnaces, leading to slow leaks and repeat failures. The OEM 10254303 is sized to Goodman's exact fittings and molded from the correct rubber compound for a durable, reliable seal. At this price, genuine OEM is the obvious choice.
Easy (1/5). A quick, tool-light repair. Power down the furnace, loosen any clamps, slide off the old coupling, seat the new 10254303 fully onto both connection points, and re-secure the clamps. Confirm the seal is snug with no gaps. Typically under 10 minutes for a homeowner.
