The Goodman 10254303 rubber coupling is a genuine OEM connector for the AMVC950905CXBA high-efficiency gas furnace and related Goodman/Amana models. It joins sections of condensate, inducer, or drain tubing with a flexible, airtight and watertight seal that absorbs vibration and accommodates slight misalignment. Cracked or hardened couplings are a common cause of condensate leaks and pressure-switch lockouts.
OEM couplings match the exact inner diameter and durometer needed to seal your furnace's tubing without collapsing or leaking. Generic rubber connectors may not fit the factory tubing sizes and can degrade quickly under heat and condensate exposure. Genuine parts ensure a lasting seal.
Easy — A 5–10 minute swap. Loosen the clamps, slide off the old coupling, and fit the new one. Disconnect power and inspect adjacent hoses before reassembly.
