The Merit Brass hex head plug is a class 150 stainless steel 316 cast pipe fitting with male National Pipe Taper (NPT) threads for closing the end of a female threaded pipe. The plug inserts into female pipes or fittings and connects with NPT threads, which create a tighter seal than straight threads, and it has a hexagonal head for increased leverage and use with a wrench during installation and disassembly. The plug 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.
