The male National Pipe Thread Taper (NPT) threaded end connects to female NPT-threaded connections. Stainless steel 303 provides better machining characteristics than stainless steel 316. The coupler meets MIL-C-4109F/A-A-59439 specifications for quick-disconnect coupling halves for hoses and portable pneumatic tools. This fitting'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). This automatic coupler allows one handed, push-to-connect operation and shuts off when disconnected. This air service only coupler is used for applications such as pneumatic tools, tire inflation, and general purpose air handling in industrial operations.
