The 45-degree elbow is a stainless steel 304 cast pipe fitting with female NPT threads for connecting pipes and fittings. The 45-degree elbow changes flow direction between pipes and has NPT threads for creating a tighter seal than straight threads. It is made from stainless steel 304, which is higher strength and more corrosion resistant than brass.
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).
