The Goodman 20201902 23-inch Condensate Drain Hose Tube is a genuine OEM replacement cut to the exact factory length for AMH950453BXAC gas furnaces. The pre-measured 23-inch run ensures the correct drainage slope from the heat exchanger to the trap without kinking or pooling — a common problem when installers substitute generic bulk tubing.
A generic hose must be measured and cut on site, and getting the length wrong causes sags that trap water and trigger overflow faults. The genuine OEM 20201902 arrives at the precise 23-inch length with the correct end fittings, so it drops in cleanly and keeps your warranty intact.
Easy (1/5). Turn off furnace power, remove the old hose, and connect the new 23-inch tube to both drain fittings. Confirm the downhill run to the trap and test for leaks. Completed in about 10 minutes with no tools required.
