The Goodman 20201902 23-inch Drain Hose Tube is a genuine OEM condensate line cut to the exact 23" length specified for the Goodman GKS90704CXAF gas furnace and related high-efficiency platforms. It carries acidic condensate from the collector box and inducer housing to the drain trap and out of the cabinet. Because this hose runs the full length of the drainage path, using the correct pre-sized OEM tube prevents the kinks, sags, and air traps that cause condensate backup and intermittent pressure-switch lockouts.

Specifications

Part number: 20201902
Length: 23 inches
Component type: Condensate drain hose tube
Compatible model: GKS90704CXAF
Application: High-efficiency gas furnace condensate drainage
Brand: Goodman (OEM)

OEM vs. Generic

The genuine Goodman 20201902 arrives pre-cut to length with the correct inner diameter to seal on OEM barbed fittings. Generic bulk tubing must be measured and trimmed by hand and frequently has a slightly different bore that either slips off under vibration or is too tight to seat fully. OEM removes the guesswork and guarantees a proper, leak-free installation.

Installation Difficulty

Easy (1 of 5). With the furnace powered down, pull the old 23" hose from both barbed connections, route the replacement along the original path, and re-secure clamps. Typically a 10–15 minute job requiring only basic hand tools. Verify the drain trap is clear while you have the hose off for best results.
