The Goodman 20201902 23-Inch Condensate Drain Hose Tube is a genuine OEM replacement for the Goodman GMH950905DXAC high-efficiency gas furnace. This 23-inch flexible tube carries acidic condensate between components of the drainage system — collector box, trap, and drain outlet. Its heat- and corrosion-resistant construction is rated for the continuous warm, low-pH condensate a 95% AFUE condensing furnace produces.
At a precise 23 inches, this OEM hose drops in at exactly the length Goodman's routing calls for, seating fully on both barbed ports with no slack or tension. Cutting generic tubing to length risks a too-short run that pulls loose or a too-long run that kinks — either causing condensate backups and leaks. The pre-cut OEM tube removes the measuring and guesswork.
Very Easy (1/5). About 10 minutes. Cut power, pull the old 23-inch hose off its fittings, press the new one on until fully seated at both ends, and check that the run is free of kinks. Briefly run the furnace and verify a leak-free drain path.
