The Goodman 20201902 is a genuine OEM 23-inch condensate drain hose tube designed for the GMV950905DXA 96% AFUE condensing gas furnace. Its precise 23" length routes condensate from the collector box to the drain trap without excess slack or tension, maintaining a consistent downhill slope. Proper condensate handling keeps the pressure switch happy and prevents water overflow that can shut the furnace down.
Cut to the correct 23" factory length, this OEM tube installs without guesswork. Generic hose requires measuring and trimming, and getting the length wrong leads to kinks, sags, or strained fittings. The genuine part ensures a clean, leak-free run every time.
Easy — pull the old 23" tube off its barbed connections and press the new one on, confirming the full run drains downhill. No tools or power required; verify all joints are secure before restarting.
