Goodman 20201802 Condensate Drain Hose / Tube

This genuine OEM Goodman 20201802 condensate drain hose is a direct-fit replacement tube for the GMV951155DXAB high-efficiency condensing gas furnace. It carries acidic condensate between the collector box, drain trap, and outlet on 90%+ AFUE furnaces. Over time these flexible tubes can crack, harden, or clog with sediment and biofilm, causing water leaks or pressure-switch faults that shut the furnace down. Replacing worn hoses during service keeps the drainage system flowing freely.

Function: Condensate transfer line for the drain system
Material: Flexible corrosion-resistant tubing
Application: Condensing (90%+ AFUE) gas furnaces
Fit: Factory-matched inner diameter and barb sizing
Fits: Goodman GMV951155DXAB and compatible condensing models
OEM Part #: 20201802

OEM vs. Generic

The OEM Goodman 20201802 is cut and sized to match the furnace's factory drain routing and barb fittings. Generic tubing may have the wrong diameter or wall thickness, causing kinks, poor seals, and leaks. Given the low cost, the exact-fit OEM tube is the easy choice.

Installation Difficulty

Rating: Easy (1/5). Power down the furnace, slip the old hose off its barbs, and press the replacement into place, ensuring no kinks and a downhill run to the trap. Typically a 5–10 minute job. Flush the drain line while access is open to prevent future clogs.
