The Anderson Metals reducing hex nipple pipe fitting is made of brass and has male National Pipe Taper (NPT) threaded connections. This reducing hex nipple fitting has one end smaller than the other for connecting two threaded pipes with different diameters, and it has a hexagonal head for an increased bearing surface when adjusting the fitting with a wrench. It has male NPT threads for connecting to female threaded pipes, creating a tighter seal than straight threads. This fitting is made of brass for corrosion resistance, ductility at high temperatures, and low magnetic permeability. Brass can be connected to copper, brass, plastic, aluminum, and welded steel. The operating temperatures for this fitting range from -53 to 121 degrees C (-65 to 250 degrees F). This fitting meets American Society for Testing and Materials (ASTM) B584 and American Society of Mechanical Engineers (ASME)/American National Standards Institute (ANSI) B16 specifications for quality assurance.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).Anderson Metals manufactures brass fittings, valves, and pipe nipples. The company, founded in 1951, is headquartered in Kansas City, MO.
