Goodman 10254303 Rubber Coupling

The Goodman 10254303 is a genuine OEM rubber coupling used to join and seal condensate drain and combustion-vent connections on the GMH950703BXAA 96% AFUE condensing gas furnace and related Goodman/Amana models. In a high-efficiency furnace the flue gases condense into acidic water, so a tight, chemical-resistant coupling is essential to prevent leaks that can damage the cabinet, control board, and surrounding structure.

Specifications

Type: Flexible rubber coupling / drain seal
Material: Condensate- and heat-resistant EPDM-style rubber
Function: Leak-proof connection for drain / vent tubing
Fits: Goodman GMH950703BXAA and select Goodman & Amana condensing furnaces
Condition: New genuine OEM part

OEM vs. Generic

The genuine Goodman OEM 10254303 is molded to the exact inside diameter and durometer needed for a proper seal on factory tubing. Generic hardware-store couplings may not resist acidic condensate long-term and can slip or weep, leading to hidden water damage. OEM ensures correct fit and service life.

Installation Difficulty

Rating: Very Easy (1/5). Slip-fit replacement — typically hand-tightened clamps, no tools beyond a nut driver. Shut off power first, then confirm the drain runs clear and leak-free after reassembly.
