For them to fill o2 and co2 you will need a mixing whip to go from scuba valve to o2 and co2. Easier to sell the scuba cylinders and purchase tanks with the correct valve. Eric

You will need : A CGA 320 tank valve. A good Machinist, who will machine said new valve, and cut threads into it, to match the threads of the removed dive tank valve. Check the fit of the new valve, and send valve and packing to the vendor, to re-cert your tank, and fill it.
