OEM Goodman part number: 20201902
Type: Condensate drain hose / tube
Length: 23 inches (factory-cut)
Fits: GKS90704CXAB and compatible 90-series furnaces
Material: Flexible, condensate-rated tubing

OEM vs. Generic

Because this hose is pre-cut to the correct 23-inch length and sized to the OEM barb fittings, it installs with no measuring, trimming, or adapters. Generic tubing must be cut to fit and often ends up too long (causing sags) or too short (stressing the connections), leading to leaks and repeat service calls.

Installation Difficulty

Easy. Remove the existing hose from the barbed ports, press the 23-inch replacement on, and secure the clamps. Roughly 10 minutes. Check that the line maintains a downward slope to the drain to prevent water backup.
