The Goodman 20201802 Drain Hose Tube is a genuine OEM condensate hose for the ACV90905DXBA high-efficiency gas furnace and compatible Goodman/Amana models. Pre-formed to route condensate from the collector box or trap to the drain, this flexible tube resists the mildly acidic condensate produced by condensing furnaces and maintains kink-free flow. Brittle, split, or kinked hoses are a leading cause of water leaks and pressure-switch faults.
The OEM hose is cut and bent to the correct length and routing for a clean, kink-free installation that drains properly. Generic bulk tubing can be the wrong diameter or stiffness, causing kinks, leaks, or poor connections at the trap and collector ports. OEM ensures a drop-in fit.
Easy (1/5). Power down the furnace, pull the old hose off its barbed fittings, and press the replacement on — secure with the original clamps if equipped. No tools needed in most cases. Under five minutes.
