Cerich,
These cylinders were a concern from the beginning and these concerns were raised about the product, and the supplier of these cylinders.
We discussed on this very forum August 22, 2014. The post was titled : "Carbon fibre scuba tank"
Carbon fiber scuba tank
Most of the relevant detail as to the cylinders in question, and an interesting link between the supplier of a
woman's muslim headgear koran and sundry muslim equipment supplier sharing the same web site and postal address
as the European dive equipment and the China export fibre wrap cylinder supplier was also discussed.
However all of these discussions were removed by the Mods it will take me some time to recover the posts
However to kick off below is the copy of one of the posts and reply from Add Helium for reference.

Just a word of caution here specifically regarding this Add Helium advert claim.
It is important to get full disclosure on these cylinders specifically for diving as they are marketed in China and designed originally for CNG (compressed natural gas) despite the oxygen label affixed.
Further albeit claiming CE the "Add Helium's" comical suggestion that these cylinders under CE exceed DOT is a most divisive and misleading statement.
1. Made in China. CE is also a meaningless acronym for "China Export"
2. The manufacturer claim only an ISO9001 QA "system"? of China Fangyuam Attest Committee
It is in my mind prudent to get additional independent testing and approval for this product or at least some research or as they say in there advert more fillers will refuse you a fill. Cant say they didn't warn you
Alternatively the Luxfer DOT cylinder is of US manufacture approval has been granted by DOT and fully approved from the most of all experienced manufacturers. To my mind these two suppliers cannot be compared save one being competent.
There is a specific reason why there is a difficulty in getting approval for fibre wrap cylinders for use underwater further more an additional difficulty in getting an oxygen content approval.
And "Add Helium" with there China Export claim both? ..Really?
Maybe you could ring this Tony and ask him for the approval certification China Export will do nicely. LOL Iain

Hello,
We make no secret they are manufactured in China. Lots of I've gear is manufactured in China. Chinese manufacture doesn't make something a bad product, provided it is done so to the specifications of the purchaser, with a good QA program.
In the case of these tanks, we do not import them from China directly. We purchase them from a European distributor who has them made to their specifications for use in diving applications and for use with 100% o2, and does their own QA.
As far as CE, these cylinders are represented to us as being CE certified. True the statement on our website that CE exceeds DOT is a bit ambiguous. These cylinders have a working pressure of 300 bar and a maximum rated pressure of 450 bar. This is far above the pressure they will see under normal use in the US (~250 bar,) and that is why we make that statement.

Can I also respectfully suggest those interested take copy of these various posts purely as a
matter of record. As I was surprised that the original post has been severely edited.
