A PVC Elbow is a type of fitting used in PVC (polyvinyl chloride) piping systems. It is a curved section of pipe that is used to change the direction of flow in a piping system. PVC elbows come in different angles, such as 90 degrees, 45 degrees, and 22.5 degrees, and are used to direct the flow of fluids, gases, and other materials in a specific direction. They are made of PVC, a type of plastic that is lightweight, durable, and resistant to corrosion, making them a popular choice for plumbing and piping applications. PVC Elbow is typically used in residential, commercial, and industrial plumbing systems, as well as in irrigation and other fluid handling systems.
