Goodman 20201901 Condensate Drain Hose Tube

The Goodman 20201901 is a factory-original condensate drain hose tube engineered for the GMH950904CXAG 96% AFUE two-stage gas furnace. On high-efficiency condensing furnaces, the secondary heat exchanger produces acidic condensate that must drain reliably — a cracked, brittle, or clogged drain hose is one of the most common causes of pressure-switch lockouts and Code 13/water-in-cabinet nuisance shutdowns. This OEM hose restores proper drainage and correct trap alignment.

Specifications

Part number: 20201901
Type: Condensate drain hose / tube
Compatible model: GMH950904CXAG (and related GMH95 / GMS95 series)
Material: Chemical-resistant flexible tubing rated for acidic condensate
Equipment: High-efficiency gas furnace
Position: Secondary heat exchanger / collector box drain

OEM vs. Generic

The genuine Goodman 20201901 is pre-formed to the exact length and bend radius of the GMH95 cabinet, so it seats without kinks or strain on the barb fittings. Universal aftermarket tubing often has the wrong wall thickness or durometer, leading to slow leaks, collapsed bends, and repeat service calls. For a drainage component that must stay leak-free for years inside the cabinet, the OEM part is the low-risk choice.

Installation

Difficulty: Easy (1/5). Power down the furnace, disconnect the old hose from the barb fittings, drain any standing water, and press the new hose fully onto each fitting until seated. Confirm the condensate trap is primed and there are no low spots that could trap water. Typical DIY time: 10–15 minutes with basic hand tools.
