Goodman 10254303 Rubber Coupling

The Goodman 10254303 is a genuine OEM rubber coupling used to make a flexible, leak-tight connection in the condensate and vent plumbing of the GMH950453BXAD 95% AFUE condensing gas furnace and other compatible Goodman and Amana models. On high-efficiency furnaces this coupling joins drain-trap and collector-box components while absorbing minor vibration and thermal movement.

Specifications

Material: Molded EPDM-style rubber
Function: Flexible leak-tight coupling for condensate/vent connections
Service: Resists acidic condensate and heat cycling
Fits: Goodman GMH950453BXAD and compatible Goodman/Amana furnaces
Part number: 10254303 (OEM)

OEM vs. Generic

The OEM 10254303 is molded to the exact inside diameter and durometer required for a proper seal on your furnace's specific fittings. Generic rubber couplings often differ slightly in size or wall thickness, which can lead to condensate leaks, water damage, or nuisance pressure-switch faults. For a few dollars, the correct OEM part is the reliable choice.

Installation Difficulty

Very easy (1/5). Slip the coupling over the fittings and secure with the existing clamps. Inspect for cracking or hardening whenever servicing the drain system, and confirm a leak-free seal before restoring operation.
