33g single canister - suitable for 165 User Activated Lifejackets
$22.00 $24.95

The 33gram single canister is suitable for Level 165 manual (user-activated) lifejackets and Level 165 automatic (water-activated) lifejackets. However if servicing an automatic lifejacket, in addition you'll need a firing mechanism and clip. (These can be purchased separately or in a pack here).

To service the manual lifejackets, all you'll need is the canister. 

Servicing instructions:

  • Firstly check the outer fabric of the lifejacket for cuts, tears, abrasion and signs of damage.
  • Then unzip the jacket so the yellow bladder is visible.
  • Unscrew the canister (don’t worry it won’t go off – and if it does by any chance its only CO2 which is what you breathe out of your mouth)
  • Check the canister for corrosion and puncture. Also check the section where it screws into the release trigger and the green clip/tab is still in place (do not pull the cord or remove the green tab). 
  • Check there is no freying on the pull cord and the whistle is still in tact.
  • Weigh the canister to comply with the minimum weight stamped on the canister itself. As long as the cylinder weighs at least this, it is fine.
  • Manually inflate the jacket through the mouth tube until fully inflated - leave inflated overnight
  • If inflated the following day, your lifejacket has no holes (which is a good start). A lifejacket that is leaking will not hold its firmness and must be replaced.
  • Screw the canister back into place tightly
  • Deflate the jacket via the end of the mouthpiece – push in end to release air
  • Repack the lifejacket as per instructions on the lifejacket, with the yellow bladder inside (don’t worry if its not packed as per manufacture).
  • Ensure manual toggle/pull cord is accessible
