What is a 180 degree return bend?

Category: 180 Degree Elbow

A 180 degree return bend is a pipe fitting that changes the direction of flow by 180 degrees, but in a U-shaped curve rather than a sharp elbow. It is often used in applications where a flow reversal is required, such as in heating and cooling systems. The dimensions of a 180 degree return bend are similar to those of a standard 180 degree elbow.
