The Goodman 20201902 is a genuine OEM 23-inch condensate drain hose/tube for the GKS90453BXAA 90%+ AFUE gas furnace. This longer, factory-cut hose spans the condensate run between the collector box or trap and the drain outlet. In a condensing furnace the water flowing through it is slightly acidic and never fully stops during a heating cycle, so hoses harden, kink, or accumulate slime over the years — causing leaks, a flooded trap, or intermittent pressure-switch faults. A fresh, correctly sized hose keeps the condensate moving and the furnace running.
At 23 inches this hose is cut and formed for the GKS90453BXAA routing, so it reaches the drain without stretching or coiling. Generic bulk tubing has to be measured and trimmed by hand and can kink at bends, while the OEM 20201902 drops in at the right length and holds proper drainage slope.
Rated Easy (1 of 5). Power down the furnace, remove the old hose from its barbs, and press the new 23" hose fully onto each fitting, keeping the run free of kinks and low spots. About 10–15 minutes with no special tools. Pour water through to confirm free drainage before restoring power.
