The Goodman 20201802 Drain Hose Tube is a genuine OEM condensate line segment built for the GKS90704CXAA high-efficiency furnace and compatible Goodman/Amana models. In a 90%+ AFUE condensing furnace, the secondary heat exchanger produces acidic condensate that must be routed away reliably. Original tubing hardens, cracks, or clogs with biofilm over years of service — replacing it restores proper drainage and prevents water leaks and pressure-switch faults.

Specifications

Type: Condensate drain hose / tube
Material: Flexible high-temp condensate tubing
Application: Internal furnace condensate routing
Fitment: Goodman GKS90704CXAA and compatible furnace platforms
OEM Part Number: 20201802

OEM vs. Generic

The OEM Goodman 20201802 is pre-cut to the correct length and inner diameter for a leak-free press fit on the factory drain ports. Generic bulk tubing often requires trimming and may not seal cleanly, leading to drips inside the cabinet. OEM guarantees a drop-in match.

Install Difficulty

Very Easy (1/5). Slip the tube onto the factory barbs — no tools required in most cases. Inspect adjacent drain components for clogs while you have the panel off.
