The Goodman 10254303 Rubber Coupling is a genuine OEM sealing component for the Goodman GCH90453BXAA high-efficiency gas furnace. This flexible rubber coupling creates a leak-tight connection between condensate, drain, or inducer-vent components, absorbing vibration while maintaining an airtight and watertight seal. On 90% AFUE furnaces, a sound coupling is essential to prevent condensate leaks and flue-gas escape that can trip pressure switches or cause water damage.

Specifications

Part type: Flexible rubber coupling / gasket seal
Material: Molded EPDM-grade rubber
Compatibility: Goodman GCH90453BXAA and related condensing furnaces
Function: Vibration-dampening, leak-proof connection for drain/vent lines
Brand: Genuine Goodman OEM

OEM vs. Generic

Genuine Goodman OEM couplings are molded to the exact diameter and durometer your furnace requires, ensuring a snug, lasting seal. Generic rubber parts may not match the inner dimension precisely, leading to slow leaks or premature cracking under heat cycling. For a reliable seal, OEM is the safer investment.

Installation Difficulty

Easy. A simple slip-fit replacement — loosen the clamp(s), remove the old coupling, seat the new one, and re-tighten. No electrical work is required. Inspect adjacent hoses and clamps for wear while you have the panel open.
