The Goodman 20201902 23-inch Drain Hose Tube is a genuine OEM condensate line cut to a factory 23-inch length for the GCH950904CXAE gas furnace and compatible Goodman/Amana condensing models. The pre-sized length reaches from the collector box to the drain trap without slack or strain, ensuring reliable gravity drainage.
As a factory-original part, this tube eliminates the trial-and-error of cutting universal line to length and guarantees the correct barb diameter for a leak-free seal.
Generic bulk tubing must be measured and cut, and an incorrect length can kink or sag, trapping condensate. The genuine Goodman 20201902 arrives at the exact 23-inch factory spec, so it installs cleanly and drains correctly the first time while preserving your equipment warranty.
Difficulty: Easy (DIY-friendly). Turn off furnace power, remove the old tube, press the 23-inch replacement onto both fittings, and confirm a continuous downhill slope to the drain. Most installs take under 10 minutes.
