Goodman 10254303 Rubber Coupling

This genuine OEM Goodman 10254303 rubber coupling is a direct-fit replacement for GKS90904CXAG gas furnaces and compatible Goodman/Amana models. The molded rubber coupling seals and connects tubing/pipe junctions in the furnace — commonly on the condensate drain, pressure-switch hose, or inducer/vent transitions — while absorbing vibration and preventing air and water leaks. Though inexpensive, a cracked or hardened coupling is a frequent cause of pressure-switch faults, condensate leaks, and nuisance lockouts, because even a small vent leak throws off the draft the furnace measures.

Specifications

OEM Part Number: 10254303
Type: Molded rubber coupling / seal
Function: Seals and isolates pipe/hose connections; dampens vibration
Material: Flexible EPDM-style rubber
Equipment: Gas furnace (Goodman GKS90904CXAG and compatible)

OEM vs. Generic

The OEM 10254303 is molded to the exact inside diameter and wall thickness needed for a leak-tight fit on this furnace's connections. Generic couplings in an approximate size can leak air or condensate and lead to intermittent pressure-switch trips. At this price point, the genuine OEM part is the obvious choice.

Installation Difficulty

Very Easy (1 of 5). With the furnace powered down, slide off the old coupling, seat the new one fully onto both connections, and secure any clamps. Takes just a couple of minutes. If you are chasing an intermittent no-heat or pressure-switch code, replacing a brittle coupling is a cheap and worthwhile first step.
