Brass Pipe Fitting, Class 125, Union, 1/2" NPT Female
This class 125 union is a brass pipe fitting with female National Pipe Taper (NPT) threads for connecting and extending male pipes. The union has NPT threads on both ends for creating tighter seals than straight threads and can usually be taken apart more easily than couplings. The class 125 fitting is made from brass, which is more economical, machinable, and offers greater corrosion resistance than steel. Class is a standard relating to tolerance, construction, dimension, and wall thickness, but it is not a direct measurement of maximum working pressure. This fitting meets standards ANSI/ASME B16.15, ASME B1.20.1, ASTM B584, and ALLOY C83600 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).
