The Anvil cap is a class 150 malleable iron pipe fitting with female National Pipe Taper (NPT) threads for closing and terminating the male end of a pipe or fitting. This cap has NPT threads for creating a tighter seal than straight threads. It is made of malleable iron, which has high tensile strength, with a black finish that resists rust in oil and gas applications. This class 150 fitting meets standards ASTM A-197, ASME B 1.20.1, 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.
