Most Primus camping gas stoves and multi-fuel expedition stoves come with a Lindal valve connector. This means they can be used with a fuel cannister/bottle that has a threaded resealable Lindal B188 valve. All the different versions of Primus gas mixes have this valve as do many other brands such as Coleman, GoSystem, and campingaz. In the technical tab for each stove we will list the valve used.
The Lindal valve cannot be used with pierceable gas cannisters.
In some countries (see map below) different valve systems are used. You may need to buy an adapter for your Lindal valve so you can use local gas cannister systems.
