The Goodman 10254303 Rubber Coupling is a genuine OEM replacement designed for the Amana/Goodman AMVC950905CXAA two-stage variable-speed gas furnace and compatible models. This flexible coupling creates a leak-free seal between condensate drain and induced-draft components, preventing water leaks and maintaining proper pressure across the combustion path. A cracked, hardened, or missing coupling is one of the most common causes of nuisance water leaks and pressure-switch faults on high-efficiency furnaces.
The OEM Goodman coupling is molded to the exact durometer and dimensions specified by the manufacturer, guaranteeing a proper seal and long service life. Generic couplings may fit loosely, harden prematurely, or fail to seat correctly — leading to repeat leaks. For a critical sealing component, OEM is the recommended choice.
Easy (1 of 5). A DIY-friendly replacement — slip the old coupling off and press the new one into place. No special tools required. Always shut off power and gas before servicing your furnace.
