The female National Pipe Thread (NPT) connection end connects to male threaded pipes. Brass is corrosive resistant, ductile at high temperatures, and has a low magnetic permeability. This plug's maximum working pressure (MWP) is 300 pounds per square inch (psi) (20.41 bar) in a temperature range from -40 to +250 degrees F (-40 to +121.11 degrees C), with a flow of 37 cubic feet per minute (CFM) at 100 psi. The valveless construction allows flow when the plug is disconnected. This plug conforms to MIL-C-4109F/A-A-59439 specifications for quick-disconnect couplings for hoses and portable pneumatic tools, but not water or fluids, at maximum working pressures up to 232 psi (16 bar).It is used for air service only.
