Goodman 20201901 Condensate Drain Hose / Tube

The Goodman 20201901 is a genuine OEM condensate drain hose designed for the GMH950453BXAD 95% AFUE high-efficiency gas furnace. High-efficiency condensing furnaces produce acidic condensate during operation, and this molded drain tube routes that moisture safely from the secondary heat exchanger and collector box to the drain system, preventing water backup, corrosion, and pressure-switch faults.

Specifications

Part type: Condensate drain hose / tube
Material: Chemical-resistant flexible tubing
Fit: Goodman GMH950453BXAD 95% AFUE condensing furnace
Application: Secondary heat exchanger / collector box drainage
Genuine OEM Goodman replacement part

OEM vs. Generic

The OEM 20201901 is molded to the exact length, bend radius, and fitting diameter of your furnace's drain layout, ensuring a leak-free connection. Generic aftermarket tubing often requires trimming and can kink or slip at the barbed fittings, leading to leaks and blocked-drain lockouts. OEM guarantees a proper, sealed fit.

Symptoms of Failure

A cracked, brittle, or clogged drain hose causes water leaks around the furnace base, pressure-switch trips, and error codes tied to condensate blockage. Replacing an aging hose during routine maintenance prevents costly water damage.

Install Difficulty

Rating: Easy (1/5). A quick 10-minute swap — release the hose clamps, remove the old tube, and press the new one onto the fittings. No tools beyond pliers required.
