I recently got a new 2.6KG CO2 bottle from KL and I ordered a new (cheap) regulator off ebay (Chinese seller). Both have arrived and all looked fine however I cannot for the life of me get the regulator to connect to the bottle, the threads look like they are same or similar size but it will just not screw on. The regulator I have been told is a size G1/2 whatever that is, anyone know the thread size on the CO2 bottles? if its different is it possible to get some sort of converter or am I just screwed with the chinese regulator?

Ive tried all ways it just wont start at all, they look very similar sizes
Just found this https://aussiehomebrewer.com/thread...-us-style-cga320-to-au-type-30-threads.96521/
I suspect I have commited the same crime, but KK charging $30 for the replacement stem and nut is even more criminal!!! I'll be making a trip to the big green shed to see if they have anything I can use.

leyther..send it back to the ebay seller and lodge a complaint with EBAY..
Bottle thread is correct AU Type-30. I'll be more careful in future, I have a micromatic for my main reg, this was only a 2nd reg for my camping bottle so I was being a bit of a tight-ass, got what I deserve, however I will lodge a complaint with ebay about selling goods not fit for the local market.
You should be able to buy a type 30 nut and change the one on your regulator. A quick look on eBay found one
Just be very careful getting the sprew out of the regulator, they are often put in with Loctite, sometimes you need a bit of heat to get it to let go, if so make sure you take all the parts off the reg that might get heat damaged. Make sure you use the right tools and think before reaching for a hammer.

Also Leyther try BOC in Cochranes road Moorabbin not far from you they will have what you want but I don't know how much.

BOC is usually insanely over priced, check a local welding supplier. G1/2 is a standard designation for BSP 1/2" I'm pretty sure.

I've seen these on eBay.
G1/2 IS BSP 1/2inch, it is an industry standard designator (the G*/*) but not what we use under Australian standards for gas handling. Bottles have the "Type ** " for various gasses. You 'should' be able to remove the stem from the regulator and replace it with the correct type but if I remember correctly they're around $50 from BOC, probably cheaper elsewhere.
