This Anderson Metals 56108 cap is a brass pipe fitting with 1/4" female NPT threads. The cap fitting closes or terminates the end of a pipe or fitting. It has female National Pipe Taper (NPT) threads for connecting to male threaded pipes, creating a tighter seal than straight threads. This fitting is made of brass for corrosion resistance, ductility at high temperatures, and low magnetic permeability. Brass can be connected to copper, brass, plastic, aluminum, and welded steel. The fitting is suitable for handling pressures up to 1,200 pounds per square inch (psi) and has an operating temperature range of -65 to +250 degrees F. This fitting meets Society of Automotive Engineers (SAE), American Society of Mechanical Engineers (ASME), American Standards Association 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).

Anderson Metals manufactures brass fittings, valves, and pipe nipples. The company, founded in 1951, is headquartered in Kansas City, MO.
