Brass Pipe Fitting Hex Coupling 3/8" NPT Female x 3/8" NPT Female Air Hose Adapter 5pcs

The reducing coupling has one end smaller than the other for connecting two pipes with different diameters. 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).
