Goodman 20201901 Condensate Drain Hose Tube

The Goodman 20201901 is a genuine OEM condensate drain hose tube built for the GKS91155DXAD gas furnace and related Goodman/Amana high-efficiency models. It carries condensate from the secondary heat exchanger and inducer assembly to the drain trap, keeping the internal drainage path sealed and correctly routed.

Specifications

Genuine Goodman OEM replacement part
Application: condensing furnace internal condensate line
Material: heat- and acid-resistant condensate-grade tubing
Pre-formed bends matched to the GKS9 cabinet layout
Direct-fit for GKS91155DXAD

OEM vs. Generic

This assembly uses factory-formed bends and precise fitting diameters that generic bulk hose cannot reliably match. An OEM 20201901 seats tightly at every connection and follows the intended cabinet path, avoiding the sagging, pooling, and slow leaks common with cut-to-length substitutes. For condensing furnaces, correct drainage is critical to pressure-switch and safety operation — the OEM part is the reliable choice.

Installation Difficulty

Easy to Moderate (2/5). Shut off power and gas, note the original routing before removal, disconnect at both ends, and install the new tube along the same path. Ensure all connections are secure and the trap is primed. Verify proper condensate flow and check for leaks before returning the unit to service.
