The Goodman 20201802 Condensate Drain Hose / Tube is a genuine OEM replacement line for the GCH950905DXAD high-efficiency gas furnace and compatible Goodman/Amana models. This flexible, molded tube routes acidic condensate between the collector box, drain trap, and outlet, keeping the condensate path sealed and leak-free. Cracked, brittle, or kinked drain hoses are a frequent cause of furnace water leaks and pressure-switch lockouts.
This OEM Goodman hose is pre-formed to the exact length and bend radius for your furnace, so it seats on the factory barbs without kinking or straining connections. Generic tubing cut to length often kinks or slips off, causing leaks. OEM fitment ensures a clean, reliable condensate path.
Easy — Power off, slide the old hose off its barbed fittings, and push the replacement into place (secure with clamps if originally equipped). A quick 10–15 minute repair for most homeowners.
Genuine OEM part. Brand names used for fitment reference only.
