Goodman 20201902 23-Inch Condensate Drain Hose Tube

The Goodman 20201902 is a genuine OEM 23-inch condensate drain hose tube for the GCH90704CXAB high-efficiency gas furnace. Cut to a precise 23" length, this high-temperature tube routes acidic combustion condensate through the furnace's drainage path between the collector box, trap, and outlet. A correctly sized hose prevents leaks, kinks, and the pressure-switch faults caused by improper drainage.

Specifications

OEM Part Number: 20201902
Length: 23 inches
Function: Condensate drainage tube
Fits: Goodman GCH90704CXAB and compatible condensing furnaces
Material: High-temperature, condensate-resistant tubing
Equipment: High-Efficiency Gas Furnace

OEM vs. Generic

This OEM hose ships at the exact 23" factory length with the correct inside diameter, so it seats securely without trimming or adapters. Generic bulk tubing must be cut and measured and may not match the bore, risking leaks. The genuine part guarantees the right fit.

Installation Difficulty

Easy — Power off, pull the old hose from its barbed fittings, and press the new 23" hose fully onto both connections. Around 15 minutes, no special tools. Route the hose without kinks and confirm a snug seal before restoring power.
