The Merit Brass hex locknut is a class 150 stainless steel 304 cast pipe fitting with female National Pipe Taper (NPT) threads for locking two fittings into place for stability and reduced
vibrations. The locknut has NPT threads for creating tighter seals than straight threads. The hexagonal shape provides increased leverage for use with a wrench during installation and
disassembly. Made of stainless steel 304, the lower carbon content of this locknut ensures higher corrosion resistance than 302 grade steel. This class 150 fitting meets steel 304 strength
standards and specifications ISO 49 and ANSI 1.20.1 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.
