The Goodman 20214203 is a genuine OEM condensate drain angle (elbow fitting) designed for the GMV950905DXBA 95% AFUE gas furnace. It redirects condensate flow at the collector box or drain trap, maintaining the correct slope so water clears the furnace instead of pooling. A cracked or clogged drain angle is a common cause of condensate overflow and pressure-switch lockouts on high-efficiency furnaces.
The OEM angle matches the factory port diameter and angle exactly, sealing cleanly against the collector box grommet. Generic elbows can be the wrong bore size, forcing tape or adhesive that eventually leaks. For a sealed condensing furnace drain path, OEM fit prevents callbacks.
Easy (DIY-friendly). Pull the old fitting, seat the new angle, and reconnect the hose clamps — about 10 minutes with the furnace powered off. No tools beyond a nut driver for the clamps.
