I have just bought a new dual regulator which was a reasonable price. However it has come with the wrong fitting for the CO2 bottle as it's of US origin. The US generally use a fitting with a CGA 320 thread whilst in the UK we tend to use a British Standard BS 341 Part 1 No. 8 thread. I need to remove the stem from the body of the first regulator which has a left hand thread which I believe is 1/4 BSP and replace the nut for the correct one for the UK. I have searched all over the internet but the only one I can find is HERE which is a lot more expensive than I was expecting. Has anyone come across one at a better price. It's my own fault not checking properly in the first place.
