Hi
I purchased a carbon fibre cylinder from Best Fittings a couple of days before the lockdown. It has a 5 year test cycle and a 15 year lifespan. Very good people to deal with. Hope this helps.
Can anyone clear-up the testing/ lifespan of the Carbon fibre charge tanks please.
I'm trying to weigh up if its worth the extra.
I read somewhere they had a 25 year life span?
Tia.

The light weight is an advantage but be aware that some dive shops don’t like them on principle.

that's interesting
I watched a you tube presentation from Pyramid air.
Apparently in the USA they have perfected a process to extend the life of carbon tanks to 30 years.
It is done for the US Navy and Fire Dept
Purchase price ÷15 years is still a reasonable equation to me.
I have two steels. The smaller is managable but 232 bar and my rifle fills to 250. Useful for top ups.
The other isnt the biggest but with a torn rotor cuff, its looking good to sell off and get a carbon fibre unit.
Handling is the main advantage of a carbon can but carbon or steel failing is gonna be a day spoiler.
To me, the steel can take a knock but I aint going to bash a carbon about.

The advantage is the weight and they are wrapped carbon around aluminium so condensation inside the bottle can't form rust which can then be a fail and need rectifying. The heads will still come under the same scrutiny which means go-no-go thread testing which can be a fail point and require a new head.
All cylinders have an unknown life. I've got some which are past 10 years, and others that didn't make it to 10 through no fault of my own, or did but wouldn't have been economical to repair (rust spot and thread stretch on one cylinder fed with dive air from a shop and moved around a lot, so a mystery)
For me weight isn't the only issue. I can fill my dumpy 3L steel off my big 12L steel several times, it's light and it doesn't take up much room, and if it's in for a test or any other issue then I have another to use.
