0.8L 3000 Psi bottle with Pi Marked Reg.

Not to be confused with other air systems fitted with cheap no name brand Chineese regs. Both the bottle AND the reg are Pi marked and fully comply with European law. 

If you have bought a bottle elseware and have been told that the reg is legal, but it is not marked, send it back immediately and ask for a full refund, it will not be legal.
