The Goodman 20201902 is a genuine OEM 23-inch condensate drain hose tube cut to length for the Goodman ACSH960453BXAA condensing furnace and compatible 96% AFUE platforms. This longer run of flexible tubing carries condensate between the heat exchanger, drain trap, and discharge connection, keeping the furnace's condensate path sealed and correctly routed across the cabinet.
This genuine Goodman OEM hose arrives pre-cut to the correct 23-inch length with the right inner diameter for your furnace. Generic tubing sold by the foot may be the wrong bore, kink at the bends, or fit loosely on the barbed fittings — risking condensate leaks and pressure-switch faults. The OEM tube seats securely and routes exactly as the factory intended.
Easy — a 5–10 minute swap. Detach the old hose from its barbed fittings, route the new 23-inch hose along the original path, and secure with the existing clamps if equipped. Shut off power before servicing. Check for kinks and confirm both ends are fully seated so condensate drains freely.
