The Goodman 20201902 23-Inch Drain Hose Tube is the genuine OEM condensate line for the GMH950904CXAC 96% AFUE gas furnace. Cut to a factory length of 23 inches, it spans the drain circuit between the condensate collector, trap, and outlet without the need to trim or splice. Reliable condensate handling is essential on high-efficiency furnaces, where flue gas condensation runs continuously during operation.
OEM vs. Generic: Length matters on condensate runs — too short and the fittings pull apart, too long and the hose sags and traps water. This OEM tube arrives at the exact 23-inch factory length with the correct inner diameter to seat on the GMH9 drain barbs, eliminating guesswork and leaks.
Install Difficulty: Very Easy (1/5). Turn off the furnace, slide the old hose off its barbed fittings, install the new 23-inch tube along the same path, and check for a snug, kink-free fit. Roughly 5 minutes, no tools required.
