The Goodman 20201802 Condensate Drain Hose Tube is a genuine OEM replacement built for the GKS90905DXAB high-efficiency gas furnace and compatible Goodman/Amana models. This flexible high-temperature hose routes condensate from the collector box and drain trap to the drain line, maintaining a clear, leak-free path for the acidic water produced during high-efficiency operation.

Drain hoses harden, kink, or crack with age and heat exposure, causing blockages, leaks, and pressure-switch lockouts. Replacing this inexpensive tube restores proper drainage and prevents water damage around the furnace cabinet.

Specifications

OEM Part Number: 20201802
Category: Drain (Condensate Hose / Tube)
Material: High-temperature flexible tubing
Function: Condensate routing to drain line

Brand: Goodman / Amana

OEM vs. Generic

The OEM hose is cut to the correct length and inside diameter with the right temperature rating for a proper slip-fit on the furnace's barbs. Generic tubing may not match the ID or high-temp requirements, risking leaks or premature failure. For a snug, reliable fit, choose OEM.

Installation Difficulty

Easy (1/5) — Slip the old hose off the barbs, route the new hose the same way, and secure any clamps. A 5–10 minute job with no special tools.

Match hose length and diameter to your unit before installing.
