Elbow is a term used in the context of pipes and piping (plumbing) to refer to fittings or pipe connections that have a shape such as an elbow or obtuse angle (90 degrees). Elbow fittings are used to change the direction of flow in a piping system or connect two pipes that form an elbow angle.
Elbows are available in a variety of materials, including steel, copper, PVC (polyvinyl chloride), and other materials to suit the needs of the application and the type of liquid or gas that will flow through the piping system. Proper use of elbows in piping is the key to producing an efficient and well-functioning system.
