The Goodman 20201802 is a genuine OEM condensate drain hose tube engineered for the AMS950904CXA high-efficiency gas furnace. This flexible, chemical-resistant tube routes acidic condensate between the collector box, drain trap, and outlet, keeping the drainage path sealed and leak-free. Over time, factory tubing can crack, harden, or clog — leading to water leaks and pressure-switch faults that shut the furnace down.
Genuine Goodman tubing is cut and formed to the exact length and inside diameter your furnace's drain routing requires, ensuring snug, leak-free connections at every port. Generic tubing may not seal properly on the OEM fittings, risking drips and airflow leaks. We recommend the OEM part for a clean, reliable fit.
Easy (1/5). Power down the furnace, slide the old hose off its fittings, and press the replacement onto the same connections. No special tools are required — just confirm each end is fully seated and secure any clamps. Run the furnace and check for leaks.
