This cartridge contains CO2, an inert gas used to inflate marine safety gear such as the two man coastal liferaft, inflatable life jackets and man overboard buoys. This non-refillable CO2 cartridge has a ½″ threaded end. It is shown at left, with a 33 gram CO2 cylinder for dan buoys and life jackets, for size comparison. This 520 gram cylinder is the replacement part which fills the two man coastal life raft on submersion. This item can only ship via ground delivery.
Do you know why CO2 is commonly used to inflate life rafts?
