The Goodman 20201902 23-Inch Condensate Drain Hose Tube is a genuine OEM replacement cut to Goodman's exact factory length for the GKS91155DXAA gas furnace and compatible Goodman/Amana high-efficiency models. Its pre-measured 23-inch run ensures the condensate line reaches the drain without kinking, stretching, or pooling — a common cause of pressure-switch faults and overflow shutdowns.
The key advantage here is length precision. The OEM 20201902 arrives at the correct 23-inch dimension with the proper inner diameter, so it drops into the factory routing path and seats cleanly at both ends. Generic bulk hose must be field-cut and often kinks at bends or slips at fittings. The OEM part removes the guesswork and the leaks that come with it.
Easy (1/5). A direct slip-in swap for the existing hose — no cutting or measuring needed. Power down the furnace, remove the old hose, and route the new one along the same path. Under 10 minutes for most installs.
