CO2 Tank and Regulator

[Daniel Vernall]

Hi I'm just about to buy the initial components for my pneumatics system but wanted to check first.

I'm looking at buying this co2 cylinder, which includes an on/off valve:

It is a brand new product, branded and made by new legion - who also make paintball guns; but I don't see any test markings on the picture.

Would I have to get this tested, or would the fact that it's brand new allow for it to be used?
