Goodman 10254303 Rubber Coupling

Keep your Goodman GMH951155DXAE high-efficiency furnace sealed and leak-free with this genuine OEM rubber coupling. Used to join condensate drain, pressure-switch tubing, or inducer/vent connection points, this flexible EPDM-style coupling absorbs vibration and maintains an airtight, watertight seal on the negative-pressure side of a 95% AFUE furnace — where even a small leak can cause pressure-switch faults and lockouts.

Specifications

Type: Flexible rubber coupling / connector seal
OEM Part Number: 10254303
Material: Heat- and moisture-resistant rubber (EPDM style)
Application: Condensate / pressure tubing / vent connection sealing
Fits: Goodman GMH951155DXAE and compatible 95% furnaces
Brand: Goodman OEM

OEM vs. Generic

The OEM 10254303 is molded to the precise inside diameter and durometer required for a positive seal on Goodman fittings. Generic hose or fuel-line couplings may fit loosely, harden prematurely, or fail to seal against condensate, leading to intermittent pressure-switch lockouts that are frustrating to diagnose. The genuine part is inexpensive insurance.

Installation Difficulty

Very Easy — A 5-minute swap. Power down the furnace, slide off the old coupling (loosen clamps if present), press the new coupling onto both connection points, and secure. No tools or minimal hand tools required. Confirm the connection is snug and leak-free before restoring power.
