The Goodman 20201802 Condensate Drain Hose Tube is a genuine OEM drainage component molded specifically for the Goodman GMH951155DXAA 95% AFUE condensing furnace. This hose carries acidic condensate between the collector box, drain trap, and outlet inside the furnace cabinet. Because the tube is pre-formed to the correct length and bend radius, it routes without kinks that would otherwise trap water and trigger pressure-switch faults.

OEM vs. Generic

The OEM 20201802 hose matches the exact inner diameter, wall thickness, and molded shape of your furnace's drain path. Generic bulk tubing must be cut to length and often kinks or slips off the barbs, causing leaks and nuisance shutdowns. The factory-formed tube installs in seconds with no guesswork.

Installation Difficulty

Very Easy (1/5). Simply pull the old hose off the barbed fittings and press the replacement into place. Cut power first and check the mating ports for debris. Under 10 minutes.

Prevent condensate leaks and error codes on your GMH951155DXAA with the genuine Goodman 20201802 drain hose tube.
