The Goodman 20201901 Drain Hose Tube is a genuine OEM condensate line for the GKS90704CXAB 90%+ AFUE gas furnace. This larger pre-formed hose carries acidic condensate through the drainage circuit with the exact length and bends the furnace was designed around, keeping the line self-draining and free of the sags that cause water backup and nuisance pressure-switch lockouts.

OEM Goodman part number: 20201901
Type: Condensate drain hose / tube
Fits: GKS90704CXAB and compatible 90-series furnaces
Material: Flexible, condensate-rated tubing
Pre-formed to factory length and routing

OEM vs. Generic

The OEM hose matches the barb diameters and routing of the GKS90704CXAB exactly, so it seals without adapters. Generic tubing must be sized by hand and can slip off fittings or kink on bends, producing intermittent leaks that are hard to diagnose. OEM removes the guesswork.

Installation Difficulty

Easy. Disconnect the old hose from the barbed ports, press the replacement into place, and reattach any clips or clamps. About 10–15 minutes. Confirm the run slopes continuously toward the drain before restarting the furnace.
