The Goodman 20201902 is a factory OEM 23-inch condensate drain hose tube built for the WGFD293090V5DAB gas furnace and related Goodman/Amana high-efficiency units. Its precise 23" length is cut to route condensate from the furnace collector box to the drain trap without excess slack or tension, ensuring smooth downhill flow and a clean, leak-free connection.
High-efficiency (90%+ AFUE) furnaces produce continuous condensate that must drain freely. A tube that is too short pulls at its fittings, while one that is too long sags and traps water. This OEM tube arrives at the correct engineered length so drainage stays reliable season after season.
Bulk generic tubing must be measured and cut by hand and rarely matches the OEM inner diameter. The genuine Goodman 20201902 comes pre-cut to spec with the correct wall thickness and barb fit — no guesswork, no leaks, no callbacks.
Easy (1 of 5). Turn off furnace power, pull the old hose from both barbed fittings, and firmly seat the new 23" tube onto each end. Roughly a 10-minute job with no tools needed. Prime the drain trap with water before returning the furnace to service.
