Detail

This hex drive countersunk plug is a brass pipe fitting with 3/8",1/2’’,1/4’’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 hex drive countersunk plug has fair vibration resistance and is suitable in low to medium pressure applications.
