The tube that failed may have been deformed,weakened due too either shipping, or the ends were fitted using a vice. Thus resulting in crushing of the cylinder when the tubes ends were fitted. The valve end should be fitted using a 8mm bar in the fill port, and a socket/spanner for the valve end. It should never be tightened in a vice. After this problem was brought to light we upgraded the fitting instructions, placing the fitting sheet around the tube, so this information could not be missed, instead of inside the packaging. Also the shipping has been upgraded to avoid any damage in transit.

We have a testing certificate from a certified testing facility of 650 bar, with rapid evacuation, and rapid refill in a 10 times cycle, with no deformation over a quantity of tubes. This is the most extreme testing you can have, as advised from the testing centre. As you are no doubt aware filling slowly,and exhausting slowly should be done in a controlled manner. The testing house inspect items on a daily basis (as you can well imagine). We have been in contact with them and the manufacturer.

In light of many potential factors of building up the unit, eg: having correct tools, fitting experience, and indeed testing capabilities once the unit has been built by the end user we are now not selling the "tube only option" to the general public. This option will only be available to accredited outlets that specialise in this field.
With over 100 tubes sold this is the only known failure. We have had a return with marks on the tube, that occurred in transit. We asked the buyer to not use the item, to return, and we replaced the tube. Upgraded packaging, and shipping has resolved this issue.

We fill every tube to 260 bar in house before shipping, and then step back to 100 bar over night too check for leaks.

We take the highest level of care, and caution from manufacture, testing, storage, packaging, and shipping to produce a safe, reliable Fenton product for the end user. We welcome any feedback from the shooting community to improve our product. Any feedback received we will certainly take it on board to help future shooters and current customers.

Are you confirming the split tube is yours then? If you are then your certificate does not seem to be worth the paper it is printed on. Again IF the tube is yours I would be considering contacting your certicate house for comment.

Also could you confirm Grade of Aluminium you use and wall thickness.

thanks
