I don't think the quality of the regulators differ depending on the type of gas they are designed for. But there _are_ different qualities of regulators available within a manufacturer's product line. I guess that's what you meant.

The CGA 320 connections are right hand threaded (not trying to be nit picky, just thought someone might want to know.)

You can use a medical gas regulator on a tank with a CGA 320 connection. I had one converted by an authorized regulator repair shop. They just removed the connector for the medical cylinder and replaced it with a CGA 320 swivel and nut.

CO2 is available in a medical gas cylinder. But you need some kind of medical certification (perhaps a prescription?) to get it refilled, according to one of the gas companies here in Hawaii. That's why I had my regulator converted.
