What type of fitting is used to change direction in piping at a 90° angle?

The type of fitting used to change direction in piping at a 90° angle is known as a 90° elbow. This fitting is specifically designed to guide flow around corners, providing a sharp angle of change. When piping systems need to navigate around obstacles or follow specific layout designs, the 90° elbow allows for an effective way to redirect the flow without having to create complex routing or additional fittings.

In various piping applications, maintaining a smooth flow is crucial for efficiency, and the 90° elbow helps achieve this without significant pressure drops or flow disturbances that could be caused by other types of fittings. This makes it an essential component in plumbing, HVAC, and other utilities where directional changes are frequently required.
