90 Degree Elbow
90 Degree Elbow
A 90 degree elbow is a pipe fitting found in plumbing and piping systems. It is intended to shift the direction of flow in a piping system by 90 degrees. This fitting is typically used to connect pipes with different sizes or to go around obstacles in a piping system’s layout while preserving a straight angle.
