This genuine Goodman 20201802 condensate drain hose tube is a direct-fit replacement for the GMH951155DXAB 96% AFUE two-stage gas furnace. As a high-efficiency condensing furnace, the GMH95 series produces acidic condensate that must be routed cleanly away from the heat exchanger and collector box — a cracked, brittle, or disconnected drain hose is one of the most common causes of nuisance lockouts, water leaks, and pressure-switch faults. This factory-spec tube restores proper drainage and keeps your furnace running reliably.
The OEM Goodman tube is molded to the exact inside diameter, wall thickness, and bend radius the GMH95 collector box requires, so it seats without kinking or leaking. Generic universal hose can be cut to length for a lower price, but often lacks the correct durometer and may collapse under vacuum, causing intermittent drain problems. For a permanent, leak-free repair we recommend the OEM part.
Easy (1/5). A basic hand tool and 10 minutes are all that's needed. Power down the furnace, note the routing, slip the old hose off the barbed fittings, and press the new tube into place. No brazing, wiring, or refrigerant work required.
