The Goodman 20201902 Condensate Drain Hose Tube is a genuine OEM 23-inch drain line formed for the GKS90905DXAF high-efficiency gas furnace. It carries acidic condensate from the trap and collector box to the drain while resisting the kinks that cause water backups. The pre-cut 23″ length is matched to the factory routing, so it drops in without measuring or trimming.

Specifications

Type: Condensate drain hose / tube
Length: 23 inches (factory cut)
Material: Flexible, condensate-safe tubing
Application: High-efficiency condensing gas furnaces
Fit: Direct OEM replacement for GKS90905DXAF
Brand: Goodman (also fits compatible Amana models)

OEM vs. Generic

This OEM hose is already the correct 23″ length and inner diameter for the factory barbs — no cutting, no mismatched fittings, guaranteed fit. A generic tube can substitute but must be measured and cut, and an oversized ID may blow off under condensate pressure and leak inside the cabinet.

Installation Difficulty

Easy (1/5). Shut off the furnace, loosen the clamps, remove the old hose, and press the new 23″ tube fully onto both fittings before re-clamping. About 10 minutes. Route it with a continuous downward slope and no dips, then run the furnace to confirm the condensate drains cleanly.
