Goodman 10254303 Rubber Coupling

The 10254303 rubber coupling is the genuine OEM connector/seal used in the Goodman GMV951155DXA 95% AFUE condensing gas furnace. On high-efficiency furnaces, flexible rubber couplings join condensate drain and pressure-sensing tubing to induced-draft and collector-box connections, maintaining an airtight, leak-free seal. Over time rubber hardens, cracks, or loosens — leading to pressure-switch faults, condensate leaks, and intermittent ignition lockouts. Replacing this inexpensive part often clears frustrating no-heat problems.

Specifications

OEM Part Number: 10254303
Type: Flexible rubber coupling / tubing seal
Fits: Goodman GMV951155DXA and compatible condensing furnaces
Material: Molded EPDM-style rubber for heat and moisture resistance
Function: Airtight/watertight connection for condensate and pressure lines

OEM vs. Generic

Genuine Goodman couplings are molded to the precise inner diameter and durometer of the original, so they seat snugly and seal completely. Loose or ill-fitting generic rubber can allow tiny air leaks that fool the pressure switch and trigger nuisance shutdowns. For a couple of dollars, the exact-fit OEM part saves hours of troubleshooting.

Installation Difficulty

Rating: Very Easy (DIY-friendly, 5–10 minutes). Power down the furnace, slide the old coupling off both fittings, clean the connection points, and press the new coupling firmly into place. Confirm a snug fit on both ends before restoring power. No tools or splicing required.

Authentic Goodman quality at a low price. Fast shipping on every order.
