The Merit Brass tee is a class 150 stainless steel 304 cast pipe fitting with female National Pipe Taper (NPT) threads for connecting and branching three sections of male pipes or fittings. It has National Pipe Taper (NPT) threads for creating tighter seals than straight threads. Made of stainless steel 304, the lower carbon content of this tee ensures higher corrosion resistance than 302 grade steel. This class 150 fitting meets standards ISO 49 and ANSI B1.20.1 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.
