Product Description

The Anvil 2120 class 3000 cap pipe fitting is made of forged steel and has a female National Pipe Taper (NPT) threaded connection. This cap fitting covers the outside of a pipe or fitting to close and terminate its end. It has female NPT threads for connecting to a male threaded pipe, creating a tighter seal than straight threads. This fitting is made of steel for weldability and rust resistance and is forged to increase the material's strength and resistance to mechanical shock and vibration. This class 3000 fitting has thick walls for resisting cracks and leaks in piping systems under high pressure. 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 American Society for Testing and Materials (ASTM) A105 and American Society of Mechanical Engineers (ASME)/American National Standards Institute (ANSI) B16.11 specifications 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).

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). Its fittings meet American Society for Testing and Materials (ASTM) and American Society of Mechanical Engineers (ASME) specifications.
