The Goodman 20201902 is a genuine OEM 23-inch condensate drain hose tube built for the GME950805CXAA high-efficiency gas furnace. This longer length is used where condensate must travel a greater distance from the collector box or inducer drain port to the trap or field drain. Its factory-matched length and fittings keep water flowing on the correct slope so the furnace drains completely and avoids pressure-switch faults caused by standing condensate.
The OEM 20201902 arrives pre-cut to the exact 23-inch length with the correct coupling diameters, so it seats and slopes properly the first time. Generic bulk tubing must be measured and trimmed, and off-spec inner diameters can slip off barbs or restrict flow. The genuine part removes guesswork and prevents leak-related callbacks.
Easy (1/5). A direct slip-on replacement. Power down the furnace, remove the old hose, route the new 23" tube to maintain a continuous downward slope, and secure both ends. No cutting or special tools needed.
