The Goodman 20201802 Drain Hose Tube is a genuine OEM condensate drainage component engineered for the Goodman ACSH960905DXAA gas furnace and compatible models. It routes condensate water away from the heat exchanger and inducer assembly, helping prevent overflow, corrosion, and water damage inside the furnace cabinet. Because it is the factory-specified part, it matches the original port diameters and routing path exactly — no trimming, adapters, or guesswork.
Generic aftermarket hoses are often cut to approximate lengths and may not seat correctly on the furnace's molded drain ports, leading to slow leaks and nuisance lockouts. This genuine Goodman OEM tube guarantees the correct bore, wall thickness, and length so connections stay tight over the life of the furnace.
Easy (1/5). Disconnect power, remove the old hose from its barbed fittings, and slide the new tube into place. Typically a 5–10 minute job requiring no special tools. Always shut off power and gas before servicing.
