A brass street elbow is a plumbing fitting used to create a right-angle change in direction of a pipe. The street elbow is designed with female threads on one end and male threads on the other end, allowing for a secure and tight connection. The brass construction ensures durability and longevity, making it suitable for both indoor and outdoor use. The street elbow provides a smooth and gradual change in direction, helping to minimize flow resistance and maintain optimal water flow.
