Merit Brass K617H-04 Stainless Steel 316 Cast Pipe Fitting, Hex Head Plug, Class 150, National Pipe Taper Thread Male (Pack of 25), 1/4"

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.

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).

Merit Brass manufactures pipe nipples following ISO 9001 standards for quality assurance. The company, family-owned since 1937 and headquartered in Cleveland, OH, distributes pipe fittings in the United States and Canada.
