The Goodman 20214203 is a genuine OEM condensate drain angle fitting engineered for the GMH951155DXAC 96% AFUE two-stage gas furnace. This molded drain elbow routes condensate away from the secondary heat exchanger and collector box, keeping the drain path correctly angled so water flows freely to the trap and out to the drain line. A cracked, brittle, or missing drain angle is one of the most common causes of nuisance pressure-switch lockouts and water leaks around the furnace base.
This genuine OEM Goodman drain angle matches factory dimensions and port geometry exactly, guaranteeing a leak-free seal. Universal generic fittings often require adapters or trimming and can misalign the drain slope — leading to standing water and repeat service calls. For a condensing furnace, an exact OEM fit is the reliable choice.
Easy (1/5) — Typically a snap or slip fit onto the existing drain port; no special tools required. Always shut off power and gas before servicing, and confirm the drain trap is clear during replacement.
