A class 150, 316 stainless steel cast pipe fitting with female National Pipe Taper (NPT) threads for connecting two sections of pipe or fittings. It has National Pipe Taper (NPT) threads for creating tighter seals than straight threads and is made of stainless steel 316, which is higher strength and more corrosion resistant than 304 stainless steel.
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.
