The Goodman 10254303 is a genuine OEM rubber coupling for the Amana/Goodman AMEH960603BXAA high-efficiency gas furnace. Rubber couplings connect and seal the condensate drain and induced-draft/vent hoses that route corrosive combustion moisture out of the furnace. On 96% AFUE condensing furnaces these connections see constant acidic condensate, so the elastomer eventually swells, cracks, or loosens — causing drips, blocked drains, pressure-switch faults, and water damage. A fresh OEM coupling restores a tight, leak-free connection.
The OEM 10254303 is molded to the correct inside diameter and wall thickness for a snug slip fit on this furnace's tubing, and its compound is rated for continuous exposure to acidic condensate. Generic couplings may be the wrong bore, may not seal fully, or may degrade quickly in the corrosive drain path. For a reliable, long-lasting seal, OEM is recommended.
Easy (1 of 5). A simple push-on replacement — power down the furnace, slide off the old coupling, and press the new one onto the tubing (secure with the existing clamp if present). No special tools required, making this an approachable DIY repair.
