Yoke regulator switch to DIN

[Sideband]

For anyone who reads this but doesn't bother to click on tonka's link, here is the short answer: For a DIN regulator you always want a 300 Bar fitting. That way it will fit either 200 Bar or 300 Bar DIN valves or manifolds.

That's not really an issue in the U.S. No U.S. manufacturers (afaik) make a 200 Bar reg connector.

battles2a5, I was with you until you said 300 bar DIN valves were better for HP or overfilled tanks. There is no functional difference in the two extra threads, vs. a 200 bar DIN valve. There are actually some 300 bar valves that are less reliable when removing the regulator because a slot has been milled into the grooves, probably thinking it would help gas to escape but will really just blow out o-rings. Oddly enough, there are now DIN plugs with a slot milled into the threads -- go figure.

Remind me, who exactly are the US regulator manufacturers again?

I was going to post that I have a buddy who has a Salvo DIN argon reg that is actually 200 bar, but Kirk beat me too it.

Where are they available that they aren't special order?

Now I ran into another question.
It's all the imperial/metric confusion!
HP is 3442 PSI is 230 bar.
LP is 2640PSI is ~180bar.
I understand that 200B DIN valve can be used on HP tank.
Who needs the 300B then anyway? For 4350PSI tanks, where are they, who's gonna fill them??

Did you read Tonka's link in post #2 (above)?

Specifically the "Frequently Asked Questions About 200 bar vs. 300 bar" section.

I did, but as far as I understand there no 300B cylinders in the US. Which makes 300B valves kinda useless to me. Though I understand standardization issues and peer-pressure.

200B versus 300B when referring to valves has absolutely NOTHING to do with the rated pressure. It's just referring to the depth of the threads on the valve, and is meaningless as far as the pressure rating is concerned.
