HPA/CO2 Threading and adaptors.

Hello, I just bought a Talon SS and wanted some advice.

I’m an amateur paintball player, obviously I don’t know much about HPA, just ask someone to fill the tanks and presto, with this purchase, my neighbor lend me a SCUBA tank to fill my Talon (he is interested in PCP’s as well), and I’m just gonna fill it some time soon.

I bought an Air Force scuba adapter, since I’m debating which power source to take, CO2 or HPA and share them between the marker and the rifle, I have a question.

Do Paintball HPA tanks come with compatible threading to the Talon SS tank?

If I buy a Pure Energy tank, do I need the Air Force CO2 adapter to fill said tank with my scuba, using my Airfoce SCUBA clamp, or does the one that came to fill the Talon tank fits?

Is there any generic connection threading, used on welder supplies that does the same function as the CO2 adapter?.

Thanks any and all replies, I want to share the powersource and I think this is the premier source of information for the Talon!
