The 90-degree street elbow is a stainless steel 304 cast pipe fitting with 1" male National Pipe Taper (NPT) threads on one end and 1" female NPT threads on the other for changing flow direction between two pipes. Made of stainless steel 304 to ensure higher corrosion resistance than 302 grade steel.

Pipe fittings are components used for connecting, terminating, controlling flow, and changing the direction of piping in many different industries. When purchasing pipe fittings, consider the application, as this will affect material type, shape, size and required durability. Fittings are available threaded or unthreaded, in many shapes, styles, sizes, and schedules (pipe wall thickness).
