Life Jacket & Vest Cartridges
Inflatable life jackets and PFDs re-arm with a CO2 cartridge that fires the instant you need it. Using the right size and thread is a safety matter — always match the spec stamped on your old cylinder or listed in your vest's manual.
Match your re-arm kit
- 16g – 25g — common for many manual and automatic inflating PFDs
- 33g, 38g, 45g — larger vests and offshore or commercial gear
Most vests take a threaded cartridge, but the thread size varies (3/8", 1/2", 5/8") — confirm before ordering.
Safety first
Re-arm with the exact size and thread the manufacturer specifies. If your old cylinder is spent, read the numbers stamped on it. Not sure? Send us the details and we'll match it.
