Need Help Converting to DIN

[lsorenson]

And not to try and derail this topic, does anyone know what the torque should be when replacing a yoke with a DIN? I would imagine it would be the same with most manufactures...

The 200 bar male end will not screw into the 300 bar female far enough to stop it from leaking.

That way, you won't use a lighter-pressure 200-bar DIN with a tank filled above 200 BAR.

However, the 300 Bar male will screw into the 200 BAR female and seal and work just fine.



No jokes, please . . . . :chuckle:

But there are adaptors with 300 bar male and 200 bar female. Or DIN 300 to Yoke.
Not sure if they are complete legal in every country but they are OK.
I have a TAG DIN 300 valve and on one side a DIN300 first stage and on the second a DIN 200 with adaptor.

The threads on a 300 bar DIN are different than the threads on a 200 bar DIN fitting. They are not ment to be interchangable.

If I remember correctly, 200 bar is the U.S. standard and 300 bar is the European standard. If you go with the wrong one you will have a hard time finding a regulator that will fit, correctely.

That must surely be wrong - otherwise a 300 bar reg would not screw into a 200 bar fitting. I have both 300 bar and 200 bar fittings, and my regs fit both.

+1 (and + at least 4 more characters so I can post...sheesh)

yes: Din 300 is just longer. So a DIN 200 Regulator can't go to the bottom of a DIN 300 valve.
For filling the DIN 300 connector of the compressor has a bigger top so it can't be fully screwed in a DIN 200 tank.
DIN is "Deutsches Institut für Normung" German Institut for Standardization. (Other say "Deutsche Industrie Norm". So whatever 200 or 300 bar it is for sure not an US thing.

That was my point. The o-ring at the end of a 200 bar regulator will not seat in a 300 bar cylinder valve so as to help prevent the use of a lower reated regulator from being used on a higher pressure cylinder and valve.

You're absolutely right. It's a pretty moot point tho, as there are virtually no regs sold in North America with 200 bar fittings anymore.

Mate that is not correct, DIN is a European standard, and has nothing to do with
America. The previous poster was absolutely correct about the 5 vs 7 threads, designed to protect the Regulator. I have 300 bar din regs and they fit the 200 bar tank valve just fine, 2 threads exposed which you hardly notice.

If you had 300bar tank valves and a 200bar reg, then the 5 threads on the reg would prevent sealing. I have never seen a 300 bar tank, although I believe they are available, similarly I have never seen a 200 bar reg?!
