This adapter is invaluable if heading further south than Germany. It converts easy-clic (non-threaded) to a threaded valve.
Decathlon is the go-to place in Europe to buy canisters, but be warned, sometimes in the stores in the south they might only have non-threaded in stock. In France the “Mr. Bricolage” chain of hardware stores are good too.
Sweden doesn’t have Decathlon, the Biltema stores are my go-to alternative.
The plastic valve-cap colour denotes the type of valve:
Red = threaded (Lindal Valve)
Green = non-threaded (Easy-Clic)
Orange is I believe only for Coleman brand stoves. Can anyone confirm?
I have read that non-threaded canisters are no longer distributed in N.America, so that’s probably why the Jeebel adapter is not available on amazon.com
On a side note, due to Decathlon’s increasing monopoly in camping gear, canisters can be hard to find elsewhere, though the huge supermarkets may have them. I have experienced Decathlon being totally out of stock of one or even both kinds of canisters.
Decathlon usually has brand name canisters (Campingaz etc) and their own brand “Forclaz” which are the same, just cheaper:

Did I mention “get an adapter”? 😁
