The Goodman 20201902 is a genuine OEM 23-inch condensate drain hose tube engineered for AMH950905DXAC high-efficiency gas furnaces. This flexible drain line routes condensate away from the secondary heat exchanger and collector box, keeping your furnace running clean and preventing water backup that can trip pressure switches or cause nuisance lockouts. Because it is the factory-specified part, it seats perfectly on the OEM barbs and matches the original bend radius, so you avoid the kinks and leaks common with universal tubing.
Our genuine OEM 20201902 tube is cut to the exact factory length and diameter, so it connects without adapters or trimming. Generic replacement tubing is often the wrong bore or stiffness, which can leak at the fittings or crimp inside tight furnace cabinets. For a leak-free, worry-free repair, the OEM part is the safe choice.
Easy (1/5). Slip the old tube off the barb fittings, route the new tube along the original path, and secure the clamps. Most homeowners complete this in under 10 minutes with no special tools. Always shut off power to the furnace before servicing.
