The Goodman 20201901 Drain Hose Tube is a genuine OEM condensate drainage component engineered for the Goodman/Amana AMS950704CXA high-efficiency gas furnace and compatible models. Condensing furnaces generate acidic condensate at the secondary heat exchanger and collector box; this factory-formed hose carries that moisture to the trap and drain without kinking or pooling, preventing pressure-switch faults and water spillage.
This genuine OEM hose is shaped to your furnace's specific internal drain routing. Substituting generic tubing risks incorrect length or bend radius, causing sags that trap water and trigger nuisance lockouts. OEM guarantees the correct fit the first time.
Easy — Remove the old hose, seat the replacement on the drain fittings, and secure the clamps. Under 15 minutes with basic pliers; no special tools needed.
