Goodman 10254303 Rubber Coupling

The Goodman 10254303 is a genuine OEM rubber coupling used to join and seal drain, condensate, and low-pressure vent connections on the GMV950453BXA high-efficiency gas furnace. In a 96% AFUE condensing furnace, flue gases cool enough to produce acidic condensate, so a leak-free, corrosion-resistant coupling is essential to keep moisture inside the drainage path and away from the burner, control board, and cabinet.

Specifications

Material: Molded EPDM-type rubber
Application: Condensate / drain / vent line coupling
Resistance: Heat, moisture, and mild acidic condensate
Fit: Goodman GMV950453BXA and compatible furnaces
OEM Part Number: 10254303

OEM vs. Generic

The genuine Goodman OEM coupling is molded to the exact inside diameter and durometer specified for your furnace's tubing, giving a slip-tight seal without over-clamping. Generic hardware-store rubber often has the wrong bore or a softer compound that hardens and cracks after repeated heat cycles, leading to condensate leaks and callbacks.

Installation Difficulty

Very easy — DIY friendly (10 minutes). Slide the coupling over the mating tubes and secure with the existing clamps. Verify a snug fit and run the furnace through a heat cycle to confirm no drips. No tools beyond a nut driver for the clamps are required.
