Explaining Street Elbows: How They Differ From Piping Elbows (PDF)

A street elbow is a type of plumbing fitting that is used to change the direction of flow in a piping system. Named for its shape, a street elbow is a 90-degree or 45-degree elbow with one male end and one female end. The male end, often referred to as the ‘street’ end, is made to fit into a different fitting or pipe, while the female end is designed to receive another pipe or fitting. The design of a street elbow allows it to connect two pipes at a corner, creating a change in the direction of liquid flow.
