They will need an scba regulator to use CGA-347 threading. It is possible to adapt a regulator to CGA fitting, but you either need a fitting to go from say CGA320(co2) to CGA 347 or you need to replace the cga stem and cga nut.
You will ONLY be able to have this filled with compressed air.
For our purposes, there isn't much use in these.
