The Goodman 20201901 Drain Hose Tube is a genuine OEM condensate hose engineered for the Goodman ACSH961155DXAA high-efficiency furnace and compatible condensing models. This pre-formed tube carries corrosive condensate between the collector box, drain trap, and drain line. Because condensing furnaces generate mildly acidic water, the factory hose uses a chemical-resistant compound that outlasts generic vinyl tubing and keeps your drain system leak-free.
The factory OEM Goodman 20201901 arrives pre-shaped and pre-cut with the precise bends and length this furnace requires, so it routes cleanly around internal components without kinking. Generic substitutes must be hand-fitted and frequently pinch or sag, causing condensate backup and nuisance lockouts. OEM is the reliable, warranty-safe choice.
Easy (1/5). Remove the existing hose from its barbed ports and press the replacement firmly onto both fittings in the same routing path. No tools required and complete in minutes. Shut off power and gas before service, then confirm free condensate flow on restart.
