The Goodman 20201902 is a genuine OEM 23-inch condensate drain hose/tube built for the AKSS920905DXAA high-efficiency gas furnace. Cut to the factory 23" length, it connects the furnace's condensate ports to the drain trap or outlet with the exact reach the cabinet requires — no measuring, trimming, or splicing needed.
The pre-cut 23-inch OEM length means a plug-and-play fit with the correct bore diameter for a tight seal. Generic bulk tubing has to be measured and cut and may not match the furnace's fitting size, increasing the chance of leaks or slip-offs. The OEM 20201902 is the fuss-free choice.
Very Easy (1/5). A 5–10 minute swap — power down, remove the old hose, press the new 23" hose onto the barbed fittings, secure clamps, and run a water test. No special tools needed.
