The Goodman 20201901 is a genuine OEM condensate drain hose tube engineered for the GME950805CXAA high-efficiency gas furnace. In a 95%+ AFUE condensing furnace, the secondary heat exchanger and collector box produce acidic condensate that must be routed safely to the drain trap. This molded drain tube carries that moisture away without kinking, sagging, or leaking, protecting the burner assembly, control board, and surrounding cabinet from water damage.
The genuine OEM 20201901 is molded to the exact bend radius and coupling diameter of the GME95 collector box, ensuring a sealed, drip-free connection. Generic universal hose can crack under condensate acidity, slip at the fittings, or fail to match the furnace's routing — leading to nuisance lockouts and water leaks. For a furnace this efficient, the correct OEM tube is the reliable choice.
Easy (1/5). Slip-on/clamp replacement in minutes with basic hand tools. Shut off power and gas, confirm the drain trap is clear, seat the tube, and secure the clamps. No special tools required.
