The Goodman 20201901 Drain Hose Tube is a genuine OEM condensate hose for the Goodman GKS90453BXAB high-efficiency gas furnace and compatible GKS90 models. It routes acidic condensate through the drain system of a 90%+ AFUE furnace, connecting the collector box, trap, and outlet. Over time the original tube stiffens and cracks from constant hot, corrosive condensate — a compromised hose leaks water into the cabinet and triggers pressure-switch faults and ignition lockouts.

Specifications

Part Type: Condensate drain hose / tube
OEM Part Number: 20201901
Application: Condensing (90%+ AFUE) furnaces
Fits: Goodman GKS90453BXAB and compatible GKS90 furnaces
Material: Molded, condensate-resistant tubing with factory bends
Brand: Goodman OEM

OEM vs. Generic

Cut-to-length generic tubing does not reproduce the molded bends or precise length of this hose, so it kinks, sags, or slips off the barbs and blocks drainage. The genuine Goodman 20201901 installs in the factory path with tight, leak-free connections — the dependable fix for furnace condensate problems.

Installation Difficulty

Rating: Easy. Shut off furnace power, remove the old hose from its barb fittings, and seat the replacement fully onto each fitting following the original routing. Check for kinks and confirm leak-free drainage on startup. DIY-friendly, though a technician can verify the full drain path.
