The Merit Brass chrome-plated brass coupling is a pipe fitting with female National Pipe Taper (NPT) threads for connecting and extending pipes going in the same direction. The fitting has female NPT threads for creating a tighter seal than straight threads. Made of brass with a high gloss, chrome-plated finish, this coupling is easier to clean than regular brass and more corrosion resistant than stainless steel. This fitting meets standards ASTM B-584, ANSI B 1.20.1, and ANSI B 16.15 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.
