Pierceable cartridges can’t be disconnected once they’ve been plugged into an appliance, so they’re suitable for more intensive or longer use – they’re also our most economical and widely available cartridges. 

However, the Campingaz 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 campingaz gas cartridge when accidentally disconnecting it from the Campingaz appliance, thereby also preventing flare-ups.
