Note:
Here is a way to fix this problem quickly: Install XC-02 onto CO2 tank by clockwise turning down (slowly and smoothly) untill you feel a pressure against to you and stop. Now, try to turn very hard and fast on the last turn. Normally, you can solve the leaking problem.

Not all CO2 tank valves are built the same and you need to do with the height of the pin located at the center of the CO2 tank valve. If you still can't solve the leaking problem, you can either buy a new CO2 tank (More than 10 brands you can choose from...) or adjust the height of pin by tools (not suggested.)
