Goodman 20201802 Condensate Drain Hose Tube

The Goodman 20201802 is a genuine OEM condensate drain hose/tube for the GKS90904CXAD high-efficiency furnace and compatible Goodman/Amana models. This flexible tube routes acidic condensate between the secondary heat exchanger, collector box, drain trap, and outlet. Over time, factory hoses can crack, harden, or clog with biofilm and scale — causing leaks and pressure-switch trips that shut the furnace down.

Specifications

Part type: Flexible condensate drain hose/tube
Function: Internal condensate routing to drain trap/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 20201802 is cut to the correct length and inside diameter for a slip-fit on the GKS90904CXAD ports, so it seals without kinks. Generic tubing may be the wrong bore or too stiff, leading to leaks or restricted flow. For an inexpensive part in a leak-critical path, OEM is the safe choice.

Installation Difficulty: Easy

Rated 1/5. Power off the furnace, pull the old hose from its fittings, and press the new tube on. No tools required; takes about 5 minutes. Inspect nearby hoses and clamps while you are in there.

Check for a snug, clamp-secured fit to avoid drips.
