The Goodman 20201802 is a genuine OEM condensate drain hose tube engineered for AMH950905CXAC high-efficiency furnaces and compatible Goodman/Amana models. It routes condensate away from the heat exchanger and secondary drain collector, preventing pooling, overflow, and moisture damage inside the cabinet. This exact-fit tube maintains proper drainage angles and seals cleanly to factory fittings.
Genuine OEM 20201802 tubing is molded to the precise length and bend radius your furnace requires, ensuring a factory-tight seal at every connection. Generic universal hoses often kink, sag, or fit loosely at the collector — leading to slow leaks and callbacks. For reliable, warranty-safe drainage, OEM is the correct choice.
Easy (1/5) — Slips onto existing fittings in minutes with basic hand tools. No brazing or wiring required. Always shut off power and drain lines before servicing.
