Seaver Safefit CO2 cartridge

SEAVER gas cartridges are screwed onto SAFEFIT vests. It is these cartridges that allow the vest to inflate in the event of a fall, thereby absorbing shock and protecting you.
The SAFEFIT vest must not be used without a gas cartridge. Only a gas cartridge adapted to your SAFEFIT vest can guarantee optimum protection in the event of the airbag mechanism being triggered.
Small cartridge 24 gr: for model XS
Large cartridge 33 gr: for models S, M, L, XL
