The Goodman 20201901 Drain Hose Tube is a factory-original condensate hose for the Goodman GMH951155DXAF 96% AFUE condensing gas furnace. It routes acidic condensate between the collector box, drain trap, and outlet on high-efficiency furnaces. Over time these hoses harden, crack, or clog with debris and biofilm — causing water leaks, drain backups, and pressure-switch lockouts. Replacing the hose during service restores proper drainage and prevents water damage around the furnace.

Specifications

Function: Condensate drain hose / connecting tube
OEM Part Number: 20201901
Brand: Goodman (also fits many Amana equivalents)
Equipment: High-Efficiency Condensing Gas Furnace
Material: Flexible condensate-rated tubing with molded barb ends
Direct fit: GMH951155DXAF

OEM vs. Generic

The OEM 20201901 is pre-formed to the exact length and bend radius Goodman specifies, so it seats without kinking or strain on the fittings. The generic equivalent is compatible condensate tubing cut to fit at a lower price — a good value when an exact molded shape isn't critical. Both handle acidic condensate.

Installation Difficulty

Easy (1/5). Slip the old hose off the barbed fittings, clear any clog, and press the new hose on until seated. Under 10 minutes. Prime the trap and check for leaks on restart. Turn off power and gas before servicing.
