The Goodman 10254303 Rubber Coupling is a genuine OEM replacement part engineered for the GKS90905DXAB gas furnace and other compatible Goodman and Amana models. This flexible rubber coupling creates a leak-tight, vibration-dampening connection between drain and condensate components, preventing water seepage and restoring quiet, reliable operation.

Over time, rubber couplings dry out, crack, or lose their seal — leading to nuisance leaks, error codes, and potential water damage around the furnace. Replacing this inexpensive part restores a proper seal and protects surrounding components.

OEM vs. Generic

Our OEM coupling matches the factory bore diameter and durometer exactly for a guaranteed seal and full compatibility. Aftermarket generic couplings offer a budget option but may vary slightly in fit and rubber quality, which can shorten service life. For a critical drain seal, we recommend OEM.

Installation Difficulty

Easy (1/5) — Hand-tool replacement in under 10 minutes. Power down the furnace, slip the old coupling off, seat the new one, and secure the clamps. No special tools required.

Always confirm compatibility with your unit's parts list before ordering.
