The Goodman 10254303 is a genuine OEM rubber coupling engineered for the AMVM960603BXAA modulating gas furnace and compatible Goodman/Amana platforms. This flexible molded coupling joins condensate and drain components while absorbing vibration and maintaining a leak-tight seal across the furnace's full operating temperature range. Using the factory-spec part ensures the correct durometer, inside diameter, and chemical resistance so the connection stays sealed for the life of the equipment.
Generic couplings often use the wrong wall thickness or a softer compound that swells and leaks after repeated heat cycles. This OEM 10254303 matches Goodman's original mold and material spec, so it seats correctly the first time and holds up to years of thermal cycling — no field trimming or double-clamping required.
Easy (1 of 5). A simple slip-on replacement that takes only a few minutes with basic hand tools. Always disconnect power to the furnace before service. If you are unsure about routing or clamp placement, consult a licensed HVAC technician.
