Can anyone tell me the correct fitting to connect to a CO2 cylinder. In the past I have used an anticlockwise thing about 20mm. The one I have now has something like 15mm connection but I cant find a thread that fits.
wee eddie, I wish to use CO2 as a freezing agent, something I have done
in the past and have the appropriate kit. Not used it for years but
as I remember the kit screwed directly
onto the gas bottle. I obtained a replacement full bottle about
8yrs ago and have not wished to use it until now.
I find that the kit does not have
the same connector as required by the new bottle.
Possibly the original had an adaptor of some kind although
I can't see the purpose of that. If that was the case then
it certainly was not big enough to have been a regulator.
Had a closer examination of the thread on the outlet valve, it looks exactly like 1/2" MI but 1/2" FI will not fit so it is not. Also it is a normal RH screw thread and not LH as I originally thought. Looking on the web for info I have failed to find out what the thread is called or where to get a fitting, something that I would have thought would be simple, perhaps it is me that is simple:-))
wee eddie, thanks for the reply. Further research says it is Whitworth 0.869 x 14 TPI which I understand, just a matter of finding a connector now which I should be able to do, thanks for trying to help .
