The Goodman 20201802 Drain Hose Tube is a genuine OEM condensate hose for AMS950905DXA high-efficiency gas furnaces. It connects the collector box, drain trap, and inducer drainage ports, carrying acidic condensate through the drainage system without kinks or leaks. Each OEM hose is cut and formed to the correct length and bend radius for this furnace chassis.
Cracked, brittle, or collapsed drain hoses cause water leaks, condensate backups, and pressure-switch faults. Replacing worn tubing with the correct OEM part keeps the drainage path sealed and free-flowing.
OEM vs. Generic: This hose is pre-formed to match the exact routing and port sizes inside the AMS950905DXA. Generic bulk tubing may be the wrong diameter or too stiff to seat properly, leading to leaks at the fittings. OEM ensures a clean, drop-in replacement.
Install Difficulty: Easy (⭐☆☆☆☆). Slide the hose onto the drainage ports and secure any clamps. Verify the routing slopes toward the drain. Power off the furnace before servicing.
