this is for the ANI 200 skull set you see in picture in case. 1.3mm with all three air caps, digital manometer in BAR that quick disconnects on and off the back of the gun that shows your air pressure in BAR and the temperature of your compressed air in °C. only used a couple times and works flawlessly. i just no longer am in the profession. comes with 3M PPS 2.0 adapter as well. Thanks for viewing, William
