Seaver Airbag Cartridge - Co2 cartridge for using in Seaver air vests. 

The gas cartridges are screwed on the airbag vests.
These cartridges allow the airbag vest to inflate in the event of a fall, thus absorbing the shock and protecting you.
The vest must not be used without a gas cartridge.
Only a gas cartridge adapted to your vest can guarantee optimal protection in the event of the airbag mechanism being triggered.
