Coleman Powermax fuel container failure

I had an MSR 8oz cartridge fail this summer. The Lyndal valve wouldn’t work with either of my stoves. The cartridge was full and I could expel gas by pusing against they Lyndal value using a screwdriver blade.

It was three weeks before I reached my next food/cartridge drop. After this experience I vowed to check all cartridges before I head out on a trip.

> Anyone ever have a failure like this?
This is very, very rare as far as I know.
Sometimes people have a problem getting the canister to mate with the stove – that happens in very cold conditions mainly. Not sure why.

> Examining the bad bottle I see the o-ring in the orifice is chewed up. I wonder if a bit got shoved down and is clogging it.
Would you be able to send me a close-up picture of this? My email is roger@backpackinglight.com, and I am the Stoves Editor here.
The ‘O-ring’ bit you are referring to is actually a neoprene washer bonded to the metal. The red plug in the middle seals against it.

If you take the canister OUTSIDE and give the red plug a poke with a BLUNT object, does any gas come out? But be VERY carefully if you try this – NO flames!
