The Goodman 20201901 Drain Hose Tube is a genuine OEM condensate drain component for the GMV950704CXBB high-efficiency gas furnace and compatible Goodman/Amana models. On a condensing furnace the drain system carries corrosive combustion condensate away from the secondary heat exchanger and collector box; a degraded or misrouted hose causes water leaks, pressure-switch trips, and no-heat lockouts. This factory tube keeps the drain path sealed and correctly shaped.
This genuine OEM hose is molded to the exact length, diameter, and bends of the GMV95 drain layout. Generic tubing requires cutting to fit and can kink or slip off if the size is off, risking leaks and callbacks. OEM delivers a guaranteed, drop-in fit.
An easy 10-minute job. Turn off power, remove the old hose from its barbed fittings, move any retaining clamps, and firmly seat the new tube on both ends. Cycle the furnace and verify condensate drains cleanly with no leaks or airflow faults.
