The Goodman 20201901 Drain Hose Tube is a genuine OEM condensate drain assembly for the Goodman ACSH960904CXAA high-efficiency gas furnace and compatible models. This pre-formed tube channels acidic condensate from the secondary heat exchanger and drain trap to the furnace outlet. A larger or multi-port routing hose than the standard connector, it is critical to proper drainage on condensing furnaces. Cracked, hardened, or clogged hoses lead to leaks, pressure switch errors, and ignition lockouts — this OEM part restores correct, leak-free flow.
This genuine OEM Goodman hose matches the exact length, port diameter, and bend geometry of your furnace's drain system. Generic tubing must be trimmed and can kink, leak, or disconnect. OEM ensures a precise, drop-in fit and a reliable seal.
Easy (1/5). Power down, remove the old hose from its barbed fittings, press the new tube fully onto each port, and secure clamps. Start the furnace and verify free condensate flow with no leaks or pressure faults.
