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.
bumpkin, slightly off subject ... I remember when all telephone exchanges [in days gone by] used to have rows of large torpedo-sized-grey-coloured cylinders of compressed air [possibly Carbon Dioxide] fitted with long tubes,valves 'n' fancy pressure gauges to all the main air-filled underground communication cables.If the air-flow from any of these 'bottles' increased by a certain amount then alarm bells would start ringing in the exchange indicating a major cable fault potentially affecting many hundreds of subscribers but thanks to the early warning alarm in the exchange this calamity was usually avoided by the expert fault-locatin' skills of the u/g maintenance telecomm engineers.
