European Certification: EN 12245

Design Life 15 Years,
15 Year Design Life is typical of the vast majority of composite cylinders available for use in the UK/EU.

5 Year cylinder hydro-static test cycle from date of manufacture. Only required if you are having the bottle commercially re-filled.

Cylinder Decommission Date:
15 Years from Manufacture Date detailed on the cylinder.
Decommission date refers to the last date that the cylinder can be filled at a commercial fill station. You can safely continue to use the cylinder after this date until the air is depleted, it just cannot be commercially re-filled.

We heard that some folks are a bit worried about how durable our carbon fibre cylinders and buddy bottles are, so we thought we would slice one in half and let you have a look inside.

As you can see, they are pretty robust, and the aluminium liner is substantial in its own right.
The carbon fibre wrap, being light weight and extremely strong, enables the liner to be much thinner than it would need to be if used alone.
So that is how they are able to be lighter than a standard Aluminium Buddy Bottle, and have a much higher pressure rating at the same time.

So now you know..

Our cylinders are CE marked and are type approved for use in the UK and European Union. They are not DOT Type approved for the US and US sub markets. Please check your specific country standards and satisfy yourself that they are suitable for your intended use. We cannot accept any return claims for unsuitability in your region.
