thats a standard scba valve,

you need a cga 347 fill station to fill your gun.



you can go cheap or expensive.

the stikman fill setup looks nice but a little pricey at 180



but whatever you do ,the first time you fill your gun ,

open the knob SLOOOOOOOOOWLY till you see how it reacts,you could easily overfill your gun quicker than you think.
