The Goodman 20201902 is a genuine OEM 23-inch condensate drain hose tube made for the AKSS920703BXAA gas furnace. Pre-cut to its factory 23" length, this flexible tube connects the furnace's condensate components and carries water to the drain outlet. Because it arrives at the correct length, there is no guesswork or trimming — it drops straight into the original routing path for a clean, leak-free fit.
The 20201902 is supplied at the exact 23-inch length and inside diameter specified for the AKSS920703BXAA, so it follows the factory bend without kinking or stretching. Generic tubing bought by the foot rarely matches the ID and can slip off heated barbs. Genuine OEM ensures a secure, warranty-safe connection.
Very Easy (1 of 5). Power down the furnace, pull the worn hose off its fittings, and push the new 23" tube fully onto each barb along the same route. Reattach clamps if used. About 10–15 minutes for most DIYers.
