The Goodman 20201802 Condensate Drain Hose Tube is a genuine OEM replacement for the GCV91155DXBA high-efficiency gas furnace and compatible Goodman/Amana models. This pre-formed hose routes acidic condensate between the secondary heat exchanger, inducer coupling box, and drain trap. Because it is cut and bent to a specific length and radius, the OEM tube seats on the correct barbs without kinking — a kinked or split hose backs up condensate and trips the pressure switch.
This genuine Goodman OEM hose arrives pre-formed to the exact length and bend for your furnace, so it connects to the factory barbs without stretching or crimping. Generic bulk tubing must be measured and cut, and the wrong durometer or diameter can slip off or collapse. OEM is the safe, drop-in choice.
Easy (1/5) — Power down the furnace, pull the old hose off its barbs, press the new hose fully onto each fitting, and confirm free drainage. No tools typically required.
