The Anderson Metals close nipple pipe fitting is made of red brass and has male National Pipe Taper (NPT) threaded connections. This close nipple fitting is a section of threaded pipe used to create a close fit between two connecting pipes. It has male NPT threads for connecting to female threaded pipes, creating a tighter seal than straight threads. This fitting is made from red brass for high strength, better corrosion resistance than stainless steel, and greater ease in machining than yellow brass. 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.
