You can also get a brass adaptor to make the industrial regulator fit the pub bottle if you can find them.... It's also worth using some ptfe tape on the adaptor thread to make it gas tight instead of trying to over tighten the thread.
I'd just like to point out that tape should only be used on tapered threads. If you need to put tape on a straight thread, then the fitting isn't seated correctly. Straight fittings don't seal on the threads. A tapered thread without tape is more likely to leak.
