Goodman 10254303 Rubber Coupling

The Goodman 10254303 is a genuine OEM rubber coupling used on the GMV950453BXBB high-efficiency furnace to create a flexible, leak-tight connection between condensate drain, trap, or vent components. On 90%+ AFUE furnaces, a sound coupling is essential — a cracked or hardened seal lets condensate weep and can trip the pressure switch or cause water damage. This exact-fit part restores the factory seal and vibration isolation.

Specifications

Part Number: 10254303
Material: EPDM/rubber
Type: Flexible Coupling / Seal
Equipment: High-Efficiency Gas Furnace
Fit: OEM direct replacement for GMV950453BXBB
Use: Condensate drain / vent connection

OEM vs. Generic

The OEM coupling is sized to the exact port diameter for a slip-on, leak-free fit. A generic rubber coupling of the same ID can work in a pinch, but off-size fittings often leak or slip loose over thermal cycles.

Installation Difficulty

Very Easy (1/5). Slip off the old coupling, clean the fitting, and press on the new one — often with a hose clamp. No tools beyond a screwdriver. Power and gas off as a precaution.
