We've brought our gas cooker from Europe, and it has a regulator with a 21mm (1/2") female connector.
I've bought a 2kg gas bottle, but this a standard 3/8" (16mm) male connector. So that doesn't fit.
I've been searching on the web for a 16 to 21mm adaptor, but I can't seem to find it. I see a lot of references to POL connectors, but that doesn't seem to be it.
Where to find an adaptor with 3/8" female to 1/2" male?
