The Goodman 10254303 Rubber Coupling is a genuine OEM condensate/drain coupling engineered for the Amana AMVC950704CXAD and other compatible Goodman and Amana high-efficiency gas furnaces. This flexible rubber sleeve creates a tight, vibration-tolerant seal between drain and condensate components, preventing nuisance water leaks that can trip float switches and cause premature corrosion inside the burner and inducer assembly.
The genuine OEM 10254303 is molded to the exact durometer and dimensions Goodman specifies, so it seats without stretching or gaps. Generic couplings often use a softer compound that hardens and cracks after a few heating seasons, leading to slow leaks. For a critical seal at this price point, OEM is the smart long-term choice.
Easy (1 of 5). No special tools required — slip the old coupling off and press the new one on. Most homeowners and technicians complete the swap in under five minutes. Always disconnect power to the furnace before servicing.
