These GoSystem Gas Cartridges contain a Butane-isobutane-Propane gas mix. This provides a power source which provides increased flame temperatures even in cold weather conditions.

The gas cartridge has the bayonet type connector or temperature sensing valve, which has been modified to make it the safest available. The automatic gas flow blocking system, the "Temperature Sensing Valve" blocks gas automatically when overheated to prevent explosion. The RVR "Rim Vent Release" is a system which in extreme situations controls gas release to prevent pressurised explosions. 

We sell these very handy and popular cartridges in singles or in value 4 packs.
