The Goodman 20201901 Condensate Drain Hose Tube is a genuine OEM part for Goodman GKS90704CXAE high-efficiency gas furnaces. This flexible tube carries acidic condensate between the collector box, drain trap, and drain outlet. Over time these hoses harden, crack, or clog with sediment and biofilm, causing leaks, pressure-switch trips, and no-heat lockouts. Replacing a degraded hose restores proper condensate flow and prevents water damage.
This genuine Goodman OEM hose is pre-cut to the correct length and inner diameter for a leak-free press fit onto the factory ports. Generic bulk tubing can be the wrong bore or too stiff, leading to poor seals and kinks that block drainage. OEM ensures the routing and slope Goodman designed for.
Easy (1–2 of 5). Slip off the old hose and press the new one onto the barbed fittings; secure clamps if used. Shut off power first and confirm no kinks that would trap water. Test drainage after startup.
