The Goodman 20201802 Drain Hose Tube is a genuine OEM condensate line for the GCH950905DXAB high-efficiency gas furnace. It routes acidic condensate from the heat exchanger and collector box to the drain trap, resisting heat, chemical attack, and kinking. Cracked, brittle, or clogged hoses cause water leaks and pressure-switch lockouts — this direct-fit replacement restores reliable drainage.
The OEM Goodman hose is molded to the correct length, bend radius, and barb diameter for your furnace, so it seats without leaks or adapters. Generic tubing may not tolerate the condensate temperature or acidity and can harden prematurely. We recommend OEM for lasting, leak-free performance.
Easy (1/5). Shut off power, pull the old hose off its barbed fittings, and press the new one fully into place — no tools required. A quick 10-minute maintenance swap.
