The Goodman 10254303 rubber coupling provides a flexible, leak-tight connection between condensate and drainage or inducer/vent components on the GME951005DXAA modulating gas furnace and related Goodman and Amana equipment. Molded from durable, temperature- and corrosion-resistant elastomer, this coupling absorbs vibration and thermal movement while maintaining a positive seal — critical on high-efficiency condensing furnaces where acidic condensate must be contained and routed reliably.
Genuine OEM 10254303 is molded to the precise inner and outer diameters your furnace requires, ensuring the clamps seat correctly and the joint stays dry. A generic coupling may fit if dimensions match exactly, but an out-of-spec coupling is a common source of nuisance condensate leaks — for a low-cost part, OEM is the reliable choice.
Easy (1/5). Loosen the hose clamps, slide off the old coupling, clean the mating surfaces, and install the new coupling with the clamps re-torqued snug. About 10 minutes with a nut driver or screwdriver. Run the furnace through a heating cycle afterward and confirm there are no drips at the joint.
