The Merit Brass stainless steel 304 coupling is a socket weld pipe fitting for connecting and extending pipes going in the same direction. The socket weld fitting has an internal recess on the inside diameter to allow for a smooth bore and better fluid flow. Made of stainless steel 304, the lower carbon content of this fitting minimizes harmful carbide precipitation during welding, ensuring higher corrosion resistance than 302 grade steel. This fitting meets standards MSS SP-114, ANSI B1.20.1, and ASTM A351 for quality assurance.

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. Family-owned since 1937, the company is based in Cleveland, OH. Merit Brass distributes pipe fittings to the United States and Canada.
