The Merit Brass half coupling is a class 150 stainless steel 316 cast pipe fitting with one unthreaded end and female National Pipe Taper (NPT) threads on the other for connecting and extending different types of pipe. The NPT threads create tighter seals than straight threads and the unthreaded end is smooth for welding to pipes. This half coupling is made of stainless steel 316, which is higher strength and more corrosion resistant than stainless steel 304. This class 150 fitting meets standards ANSI B1.20.1 and ISO 49 for quality assurance. 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.
