The Goodman 20201902 is a pre-cut 23-inch condensate drain hose tube engineered for the GME950403BXAB 96% AFUE gas furnace. Its factory length reaches from the collector box or inducer outlet to the condensate trap without stretching or sagging, keeping a continuous downward slope so water drains freely and the pressure switch stays satisfied. A hose that is too short, too long, or of the wrong bore is a common cause of nuisance furnace shutdowns.
Cutting bulk tubing to length rarely matches the OEM inside diameter and bend radius, causing weak barb seals and traps that hold standing water. This genuine Goodman OEM 23-inch hose arrives at the correct length with the proper wall thickness, dropping in as a true factory replacement.
Easy (1/5). Power down the furnace, remove the old hose from both fittings, press the new 23-inch tube onto the barbs, and reseat the clamps. No special tools required. Verify the drain path is clear and sloped before restoring power.
