DIN conector norm for scuba diving

[phgachoud]

Just bought a JJ-CCR (not arrived yet) and need to setup a oxygen tank 15m3 to the 3L DIN O2 tank. I saw there is a european norm for O2 tanks with M26x2 which I didnt choose for compatibilty reasons (am in Chile). My Q is is there one and only one DIN norm for scuba tanks and material or many? if many which ones?

Would that be compatible with the JJ tanks?
And what kind of adapter do I need from the O2 tank to get to female DIN?
Thx for your help

You are going to see few if any M26 tanks outside the EU. And from what I hear M26 isn't super common in the EU outside commercial diving.

If you ordered it through your instructor then your instructor should have asked you want valve you want and if you instructor was on the ball he would have ordered you a regular DIN valve O2 tank.

JJ sells the unit setup for the EU with an M26 or they sell it for the "international" market with a regular DIN valve. The valves that come with your JJ are Nautec inline valves. Very nice valves, probably the best valves money can buy.

So yes if your instructor ordered you a regular 5/8" DIN valve then the whip you posted a picture of will work.
