Life Jacket CO2 cylinder - 33g. Suits most 150 newton inflatable life jackets. A 33-gram CO2 cylinder is used to inflate an inflatable life jacket. When the life jacket is activated, the CO2 cylinder is punctured and the gas rushes into the inflatable bladder, causing it to expand and fill with air. Dimensions: 1/2" thread base. Length is 138mm

• Always inspect your life jacket before using it to make sure that it is in good condition and that the CO2 cylinder is not damaged or corroded.
• Do not activate your life jacket unless you are in the water.
• An annual inspection is required to ensure your cylinder is still in working order.
