This coupling is a class 3000 forged stainless steel 304/304L pipe fitting with female National Pipe Taper (NPT) threads on both ends for connecting and extending pipes of same sizes going in the same direction. This class 3000 coupling has been forged for durability and is made from stainless steel 304/304L for corrosion resistance. Class is a standard relating to tolerance, construction, dimension, and wall thickness, but it is not a direct measurement of maximum working pressure.

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).
