The Goodman 20201902 23-inch Drain Hose Tube is a factory-original condensate hose for the Goodman GMH951155DXAF 96% AFUE condensing gas furnace. This longer 23" run carries acidic condensate between the collector box or trap and the drain outlet. As the hose ages it stiffens, cracks, or plugs with sediment and biofilm, leading to leaks, slow drainage, and pressure-switch faults. Swapping in a fresh hose during maintenance keeps the condensate path clear and protects the furnace cabinet from water damage.

Length: 23 inches
OEM Part Number: 20201902
Brand: Goodman (also fits many Amana equivalents)
Equipment: High-Efficiency Condensing Gas Furnace

OEM vs. Generic

The OEM 20201902 comes pre-cut to the correct 23" length with the proper barb ends for a clean, kink-free routing. The generic equivalent is compatible condensate tubing sized to fit at a lower cost — fine when you can trim to length yourself. Both are rated for acidic condensate.

Installation Difficulty

Easy (1/5). Pull the old hose off its fittings, clear any blockage, and press the new 23" hose into place until fully seated. About 10 minutes. Check routing for kinks and confirm no leaks on restart. Shut off power and gas before servicing.
