I was wondering if you or anyone else knows of an adapter to use a US regulator on the CO2 tanks here in Japan?
The adapter is to connect it to a 74 gram cartridge!! Why would you make an adapter for a full size regulator to a small canister, but not one for a full size can:/
I am not sure what the problem is. I thought you were looking for an adapter that would allow your US regulator with a CGA320 connector to fit the Japanese "Standard" (which is probably the strange 74 gram cartridge)?
Anyway they said that I would have to buy that adapter and another for a full size adapter. Do you think it would be an ok Idea to use two adapters for the regulator?
There should be no problem using multiple adapters.
I read somewhere on a Homebrew forum where an American stationed in Okinawa found an adapter, but he only gives directions there from his base, so they definitely exist.
Perhaps you should ask him where he managed to find his adapter?
