Is the cylinder volume correct for the capacity of the LJ?
Lifejacket leaking - Hanmar Automatic
- Thread starter Ammonite
- Start date

Yep, 33g.

What model is the Hammar unit? In my case it was an A1 that failed (twice) and the issue was supposed to have been resolved with the MA1. I think the latest version is the M2.

I should add that
The reason I'm exercised about this is that my Spinlock Vito LJs are also fitted with the same unit. I don't believe the chances of extreme failure like this should go up dramatically after expiry. Sure, they're well out of date but the date should indicate the crossover between guaranteed success and some chance of failure, not "high chance of failure".
It's the A1 mod. The other failure I had a couple of years back was also an A1. They are fitted to Crewsaver LJ but I don't think that's relevant.

Both of mine were in date when they failed and had been well maintained. My personal view is that the problem with the A1 is much more widespread than I was told and that the design is flawed. I obviously don't have the data to back that up, however having both jackets fail is enough to convince me.

Good lord! No wonder you have a problem.

Inflation test annually is what's recommended...

Failure of cylinders that have partly unscrewed is a well known problem. I know that is not your issue.
Recent LJs should have an additional retention system. I would use thread lock on older type LJs to prevent the cylinder coming undone

For the spares do consider RT Supplies Products Archive - RT Supplies Ltd
I was put onto them in an earlier thread (they do not readily come up in a search engine). Not only can you select the bits required but he also provides the expiry dates of the goods that he is selling on the web site - which are very good IMHO. Good postal service too...
