The Goodman 20201902 is a genuine OEM 23-inch condensate drain hose tube for the WGFM295090V5DAA high-efficiency gas furnace and compatible Goodman/Amana condensing models. Cut to the factory 23" length, it spans a specific run in the drain assembly so condensate reaches the trap with proper slope. Pre-sized OEM tubing eliminates the guesswork of trimming generic hose and ensures the clamps land on clean, sealed barb fittings.
Because this part is length-specific, the OEM 20201902 drops in without measuring or cutting, and its wall thickness resists kinking at the routed bends. Generic bulk hose must be trimmed on site and often has the wrong ID, risking leaks and improper drainage slope. OEM guarantees the right 23" run every time.
Easy — DIY friendly (approx. 15 minutes). Shut off the furnace, remove the old 23" tube, and install the new 20201902 along the original route. Secure both clamps, verify a downhill path to the drain, and wet-test for leaks before returning the unit to service.
