The Campingaz C206 gas canisters are suitable for a huge range of camping stoves, lanterns and burners, manufactured by Campingaz themselves, or Coleman, or many other brands too. The C206 canister is pierced by the stove when fitted, so cannot be removed from the stove until it is empty. However, the C206 GLS cartridge has a new integrated flow reducing system, the Gas Lock System, which is compliant to the new European standard EN 417:2012 legislation. The system prevents the majority of residual gas from escaping the cartridge when accidentally disconnecting it from the appliance, thereby also preventing flare-ups. Make sure that you buy the right type of canister to fit your stove or burner. Contains a butane/propane mix.Functional gas cartridge from CampingazGas Lock System - this integrated flow reducing system prevents the majority of residual gas from escaping the cartridge when accidentally disconnecting it from the appliance, thereby preventing flare-ups.Gas Lock System is compliant with new European standard EN 417:2012 legislation80/20 butane/propane gas mixSelf-sealing cartridge - with safety valveCompatible for Campingaz Bleuet Micro, Twister, Lumogaz, Lumostar, Bivouac and Party Grill
