This permanent O-Ring is a great option when your regulator does not have a built-in o-ring. It screws into the CGA-320 Co2 tank valve and creates a good seal to help prevent air leaks what could arise in a metal on metal connection. It attaches directly to all Sherwood GV Series and Intermed cylinder valves, no drilling or tapping needed.
