The genuine Goodman 20214203 drain angle is the molded elbow fitting that directs condensate flow at the collector box or drain trap of your furnace. It is a precise-fit replacement for the Goodman GCH950453BXAA and related high-efficiency models. When this fitting cracks or its gasket hardens, you'll see water pooling under the unit or intermittent pressure-switch trips — this OEM part restores a sealed, correctly angled drain path.
This genuine Goodman angle matches the factory port geometry and sealing surface exactly. Generic elbows rarely match the collector-box thread and O-ring profile, which invites slow leaks that can corrode the heat exchanger over time. Choose OEM for a guaranteed water-tight fit and warranty peace of mind.
Easy to Moderate. Shut off power and gas, disconnect the drain hose, remove the old angle from the collector box, seat the new fitting with its seal, and reconnect. A basic 15-minute repair; verify no leaks on first heat cycle.
