The Goodman 20201802 is a genuine OEM condensate drain hose tube engineered for the GMV950704CXA 95% AFUE two-stage gas furnace. This flexible drain line routes acidic condensate away from the secondary heat exchanger and collector box, keeping the drainage circuit sealed and free of leaks. Because it is a factory component, the fitment, bend radius, and connection diameters match the original part exactly — no trimming or adapters required.
Generic drain tubing is often cut to a universal length and can kink, sag, or crack when exposed to condensate acidity over time. This genuine OEM tube is pre-formed to the furnace's drain layout and molded from material rated for continuous condensate contact, protecting your warranty and preventing water damage from clogs or overflow.
Easy (1/5). A basic DIY replacement — power down the furnace, disconnect the old hose at both ends, seat the new tube, and verify a tight, drip-free seal. Typically 10–15 minutes with no special tools.
