The Goodman 20201902 23-inch Condensate Drain Hose Tube is a genuine OEM replacement for GCH90904CXAA condensing gas furnaces. Cut and molded to the exact 23-inch factory length, this hose carries condensate from the furnace's drain manifold to the trap and floor drain. Using the correct length avoids the sagging, pooling, and kinks that cause slow draining and pressure-switch faults on high-efficiency equipment.

Specifications

OEM Part Number: 20201902
Length: 23 inches (factory pre-cut)
Part Type: Condensate drain hose tube
Brand: Goodman
Equipment: Gas furnace (condensing / 90%+ AFUE)
Compatible Model: GCH90904CXAA

OEM vs. Generic

The genuine 20201902 arrives at the precise length and diameter your furnace expects, so it seats cleanly on the OEM barbs without splicing or clamps that can leak. Generic bulk hose requires field measuring and cutting, and an incorrect length can trap air or hold standing water. For a clean, code-compliant drain path, OEM is the safe pick.

Installation Difficulty

Easy (1/5). Roughly a 10-minute job. Turn off power, pull the old 23-inch hose from its fittings, press the new tube onto the barbs, and confirm a continuous downhill slope to the drain. Test drainage by running the furnace through a heat cycle and watching for free flow at the trap.

Compatibility note: Verify your furnace tag shows GCH90904CXAA. Reach out to info@nationalhvacparts.com for fitment help.
