In plumbing, what is the role of the 90-degree street elbow?

The 90-degree street elbow is specifically designed to change the direction of flow in piping systems. This fitting allows for a smooth transition in the piping layout, making it possible to redirect the flow without the need for additional fittings, which can save space and reduce the number of connections required. Its unique shape allows it to fit directly onto a pipe while connecting to the next piece of plumbing, such as another pipe or a fixture, ensuring a secure and efficient flow path. With plumbing systems often needing to navigate around corners or obstacles, the use of a street elbow facilitates these necessary changes in direction effectively.
