The Goodman 20214203 is a genuine OEM condensate drain angle fitting designed for the ACSH960904CXAA high-efficiency gas furnace. This molded elbow redirects condensate flow from the collector box or drain trap, allowing the furnace to be vented and drained in tight installation spaces. The factory geometry maintains the correct drainage angle so water never pools against the pressure switch ports.
The genuine Goodman OEM angle matches the exact barb size and bend radius of the ACSH960904CXAA drain system, ensuring a snug, leak-free connection. Generic elbows may have mismatched inner diameters or sharper bends that restrict flow and cause condensate backup. Because improper drainage is a leading cause of furnace lockouts, fitting the OEM part protects against avoidable service calls.
Easy (1/5). Press the angle fitting onto the drain barb, secure with the original clamp, and verify the downstream hose slopes toward the drain. Typically a 5–10 minute job with no special tools. Always turn off power and gas before working on the unit.
