The Goodman 20201901 Condensate Drain Hose Tube is a genuine OEM replacement for the GCV91155DXBA high-efficiency gas furnace and compatible Goodman/Amana models. This pre-formed drain hose carries corrosive condensate from the collector box and secondary heat exchanger to the condensate trap. The factory bend radius and length keep the tube kink-free in the tight furnace cabinet, preventing the condensate back-ups that cause pressure-switch lockouts and water damage.
This genuine Goodman OEM hose is molded to the exact length and curvature your furnace requires, so it seats on the factory barbs without stretching, cutting, or splicing. Generic tubing risks the wrong inside diameter and can slip off under condensate flow. For a reliable seal, choose OEM.
Easy (1/5) — Shut off power, remove the old hose from its fittings, push the new hose fully onto each barb, and verify condensate drains freely to the trap. Typically no tools needed.
