Goodman 10254303 Rubber Coupling

This genuine OEM Goodman 10254303 rubber coupling is a small but essential sealing component for the GMH950703BXAF 96% AFUE condensing furnace. On high-efficiency furnaces the coupling joins sections of the condensate drain or inducer/collector plumbing, providing a flexible, leak-tight connection that absorbs vibration and accommodates slight misalignment. A cracked, hardened, or missing coupling leads to condensate leaks, drain-line air leaks, and potential pressure-switch faults that keep the furnace from firing.

Specifications

Type: Flexible rubber coupling / seal
Application: Condensate drain / plumbing connection
Material: EPDM-style rubber, condensate-rated
Fits: Goodman/Amana GMH950703BXAF and compatible furnaces
OEM Part Number: 10254303

OEM vs. Generic

The OEM 10254303 is molded to the exact inside diameter and durometer needed for a sealed, slip-free fit on your furnace's fittings. Generic hardware-store couplings often differ in size or wall thickness, causing slow leaks that are hard to trace. For a reliable, drip-free seal, use the genuine Goodman part.

Installation Difficulty

Rating: Easy (1/5). This is a quick 5–10 minute job requiring no special tools. Power down the furnace, slide off the old coupling (and its clamps if used), press the new coupling fully onto the fittings, and re-secure the clamps. Run the furnace and confirm no condensate leaks at the joint.
