Anvil 8700131454, Malleable Iron Pipe Fitting, Hex Bushing, 2" NPT Male x 1-1/2" NPT Female, Galvanized Finish The Anvil hex bushing is a class 150 malleable iron pipe fitting with male National Pipe Taper (NPT) threads on the outside and female NPT threads on the inside to connect two pipes of different sizes. It has NPT threads for creating tighter seals than straight threads and a hexagonal head for increased leverage and use with a wrench during installation and disassembly. This bushing is made of malleable iron, which has high tensile strength, with a galvanized finish that provides corrosion resistance for water, steam, and air applications. This class 150 fitting meets standards ASTM A-197 and ASME B 16.3 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).Anvil International provides pipe products and design services. The company, founded in 1850 and headquartered in Portsmouth, NH, meets International Organization for Standardization (ISO) 9001:2000 standards and is certified by the American Petroleum Institute (API).
