M25x2 valves for Faber steel tank

[Bashir baba]

hello
I just bought a new faber steel tank from Istanbul Turkey and the valve that was given to me is M25x2 which I did not install yet on the tank
I noted that my DIN connection on my first stage regulator which is rated for 300 bar has a smaller diameter than the opening on the valve neck which means I can not use it

Any one can advise how to resolve this issue
Thanks

Salam,

Was the Tank valve a DIN or Yoke/INT valve? Send pics of all of what you have.

The tank valve is DIN and I just found the answer
As my tank valve is rated for oxygen my DIN connector must meet that afound the piecs with larger diameter and installed it

Thank a lot for your reply and support
