The 1/2 x 3/8 Barstock Reducer Street Elbow is a pipe fitting designed to change the direction of flow between pipes of different sizes, specifically from 1/2-inch to 3/8-inch. Made from barstock material, this fitting is crafted from solid metal for superior strength and durability compared to cast fittings. It features a reducer design, which allows for the transition from a larger pipe to a smaller one, and a street elbow design, meaning one side has a male thread and the other has a female thread.
