(Take out the hose and install a standard 1/4" SAE fare fitting).

I just looked on-line and these are getting harder to find..
This is stuff I had on hand for air rifles, so I used it.
CO2 tanks attach also and can be used for brazing copper (instead of nitrogen).

Here's a link to some of my first install..
