Goodman 20201901 Condensate Drain Hose Tube

The Goodman 20201901 is a genuine OEM condensate drain hose tube for the GKS90453BXAC 90%+ efficiency gas furnace. This larger drain assembly carries acidic combustion condensate from the collector box and inducer housing to the drain trap and out of the unit. Because condensing furnaces continuously produce water during heating, a correctly fitted OEM drain path is critical to prevent leaks, corrosion, and pressure-switch faults.

OEM Part Number: 20201901
Compatible Model: GKS90453BXAC and related GKS9-series furnaces
Function: Primary condensate drainage line
Material: Chemical-resistant flexible tubing
Brand: Goodman (genuine OEM)

OEM vs. Generic

The 20201901 is molded with the specific inner diameter and length needed to mate cleanly with the GKS90453BXAC's collector box ports. Generic tubing frequently mismatches the barb size, allowing slow drips that pool inside the cabinet and rust the burner assembly. The OEM part eliminates guesswork and installs with confidence.

Installation Difficulty

Rating: Easy (1/5). A hand-fit slip-on replacement requiring no special tools. Power down the furnace and shut off gas, remove the failed tube from the collector box and trap, then seat the new 20201901 firmly onto each fitting. Verify the drain trap is clear and test for leaks on the next heating cycle. Typical job time is 10–15 minutes.
