Goodman 10254303 Rubber Coupling

The Goodman 10254303 is a genuine OEM rubber coupling used to create a flexible, leak-tight connection in the condensate and combustion-air pathways of the GMH950905DXAE 95% AFUE furnace. High-efficiency furnaces produce acidic condensate, and a properly sealed coupling prevents leaks that can corrode components, trigger pressure-switch faults, or cause water damage around the unit.

Specifications

Part number: 10254303
Type: Molded rubber coupling / seal
Material: Condensate-resistant EPDM-style rubber
Fits: Goodman GMH950905DXAE and compatible condensing furnaces
Function: Flexible leak-tight drain / draft connection

OEM vs. Generic

OEM couplings are molded to the exact inside diameter of the furnace's tubing and drain fittings, so they seat fully and seal without over-clamping. Generic couplings may not match the durometer or bore, leading to slow leaks and repeat service calls. At this price point, the OEM part is the clear choice.

Installation Difficulty

Very Easy — slip-fit replacement secured with the existing hose clamps, typically under 10 minutes. Power and gas should be off during service. Inspect adjacent tubing for cracks while the coupling is removed.
