The Merit Brass nipple is a seamless schedule 40 red brass pipe fitting with male National Pipe Taper (NPT) threads for connecting and extending female threaded pipes. The fitting has NPT threads for creating tighter seals than straight threads. Made of red brass, this schedule 40 seamless nipple is easier to clean than regular brass and more corrosion resistant than stainless steel. Seamless pipe is produced from a solid piece of metal that is heated and moved over a form until the steel is shaped into a hollow tube. It can withstand pressure better than ductile or welded pipes. The nipple meets standard NSF/ANSI 61 for use with drinking water supplies of pH 6.5 and higher and ASTM B-687 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.
