The Goodman 20201802 Drain Hose Tube is a genuine OEM condensate hose for the Goodman ACSH961155DXAA high-efficiency furnace and compatible condensing units. It routes acidic condensate between the coil/collector box, the drain trap, and the field drain line. The factory hose is molded from chemical-resistant material that resists the corrosive condensate produced by 90%+ AFUE furnaces, preventing the cracking and leaks common with hardware-store tubing.
This is the factory OEM Goodman hose, pre-cut to the correct length with the exact inner diameter for a leak-free press fit on Goodman trap and collector ports. Generic tubing requires field cutting and often slips or kinks, leading to overflow and pressure-switch faults. OEM ensures a clean, reliable connection.
Easy (1/5). Pull the old hose off its barbed fittings, slide on the replacement, and confirm a snug seat at both ends. Takes only a few minutes with no tools. Turn off power and gas first, and verify condensate drains freely after restart.
