Goodman 20201902 23-Inch Condensate Drain Hose Tube

The Goodman 20201902 is a genuine OEM 23-inch condensate drain hose/tube for the GKS90904CXAD high-efficiency furnace and compatible Goodman/Amana models. This pre-cut length routes acidic condensate from the collector box or trap to the furnace's drain outlet. The 23-inch factory length ensures the correct slope and reach without splices — hardened or clogged tubing here leads to leaks, biofilm buildup, and pressure-switch shutdowns.

Specifications

Part type: Pre-cut flexible condensate drain hose/tube
Length: 23 inches (factory-specified)
Function: Condensate routing to drain outlet
Fits: Goodman GKS90904CXAD and compatible 90%-AFUE furnaces
Material: Heat- and acid-resistant flexible tubing
OEM manufacturer: Goodman / Amana

OEM vs. Generic

The OEM 20201902 arrives at the exact 23-inch length and correct bore for the GKS90904CXAD, so it installs with proper drain slope and no guesswork. Cutting generic bulk tubing risks the wrong length or a poor seal at the ports. OEM saves time and prevents drainage problems.

Installation Difficulty: Easy

Rated 1/5. Turn off furnace power, remove the old hose from its fittings, and press the new 23-inch tube into place along the original route. No tools needed; about 5–10 minutes.

Ensure the full run slopes downward to the drain for reliable flow.
