This Anderson Metals 38104 union is a red brass pipe with 1" male threads. The union fitting has three pieces and includes a threaded connection that can be screwed or unscrewed to connect or disconnect pipes more easily than with a coupling. It has female threads for connecting to male threaded pipes. This fitting is made from red brass for high strength, better corrosion resistance than stainless steel, and greater ease in machining than yellow 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).

Anderson Metals manufactures brass fittings, valves, and pipe nipples. The company, founded in 1951, is headquartered in Kansas City, MO.
