The Merit Brass class 125 coupling is a lead-free brass pipe fitting with female National Pipe Taper (NPT) threads for connecting and extending pipes going in the same direction. It has female NPT threads for connecting to male pipes with a tighter seal than straight threads. Lead-free brass is comparable in strength to stainless steel and is more corrosion resistant. This class 125 fitting meets standards ASTM B-584-06 (C89833), ANSI B 1.20.1, and ANSI B 16.15 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. Family-owned since 1937, the company is based in Cleveland, OH. Merit Brass distributes pipe fittings to the United States and Canada.
