This Anderson Metals 06115 hex drive countersunk plug is a brass pipe fitting with 3/4" male NPT threads. The countersunk plug with a hex drive inserts into a pipe or fitting to close and terminate its end and has a recessed hex head for increased bearing load. It has male National Pipe Taper (NPT) threads for connecting to female 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 countersunk hex drive plug has fair vibration resistance and is suitable in low to medium pressure applications.

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.
