The Goodman 10254303 Rubber Coupling is a genuine OEM sealing coupling engineered for the Goodman/Amana AMH950704CXAE gas furnace and compatible 95% AFUE models. It creates a leak-tight connection in the condensate/drain path, preventing water seepage and combustion-air leaks that can trip pressure switches or cause nuisance shutdowns.
Choosing the OEM 10254303 guarantees an exact dimensional and durometer match, so the coupling seats fully and holds its seal across thermal cycling. Generic aftermarket couplings are cheaper but often run slightly out of spec, leading to slow drips, condensate pooling, and premature cracking. For a critical sealing component this small, OEM is the low-risk choice.
Easy (1/5). Slips over the drain fitting and secures with the existing clamp — typically a 5-minute swap with no special tools. Always shut off power and gas before servicing.
