Gas bottle connection

[LordEoin]

Anyone know if the connection on a gas bottle is cga320 or w218-14 ?

CO2 cylinder?

It's W21.8-14 over here. The other one is standard in the US. So you'll need an adapter if you're buying a US regulator to fit an Irish/uk gas bottle.

excellent, thank you.

Munster CO2 said it wouldn't pay him to turn the machine on to fill these even if he had the connector.
