The Goodman 20201902 is a genuine OEM 23-inch condensate drain hose tube built for GMS950704CXA 95% AFUE gas furnaces and compatible high-efficiency models. Its precise length ensures the condensate drain reaches the collector box, trap, or drain pan without stretching, kinking, or coiling — the leading causes of drainage backups and pressure-switch faults.
Cutting generic tubing to length rarely matches the factory routing, and the wrong inner diameter can restrict flow. The OEM 20201902 arrives pre-cut to the exact 23-inch length Goodman engineered for this furnace, eliminating guesswork and ensuring reliable condensate drainage.
A quick 10-minute replacement. Turn off furnace power, detach the old hose from both fittings, route the new 23-inch tube along the original path, secure any clamps, and verify a downhill drain with no kinks. Verify the part number against your unit before installing.
Replacement part only. Professional installation recommended if you are not comfortable servicing HVAC equipment.
