The Goodman 10254303 Rubber Coupling is a genuine OEM sealing component used in the condensate drain and trap assembly of the GMH950704CXAA 95% AFUE condensing gas furnace. In high-efficiency furnaces, flue gases condense into acidic water that must drain cleanly — this flexible rubber coupling creates a leak-free connection between drain fittings and the collector box or trap, absorbing vibration and thermal movement without cracking.

Part number: 10254303
Type: Rubber coupling / drain grommet seal
Material: High-temp EPDM-style rubber
Function: Seals condensate drain / trap connections
Fits: Goodman GMH950704CXAA and compatible GMH95 furnaces

OEM vs. Generic

The OEM Goodman 10254303 is molded to the exact inner and outer diameters of the factory drain path, ensuring a watertight seal. Our generic equivalent offers a comparable durometer rubber at a lower cost for general-purpose sealing.

Installation Difficulty

Very easy (1/5). Slide the old coupling off and press the new one on — no tools required. A worn or hardened coupling is a frequent cause of condensate leaks and P-trap drips; replacing it proactively during annual service prevents water damage and rust.
