There something odd about that regulator fitting. It kind of looks like a DIN fitting, but there is no O-ring or O-ring groove.

I do have an old Draeger twin tank manifold from a set of 1957 tanks that had a DIN fitting with a Phenolic washer rather than an O-ring, is this supposed to be the same or is it a different fitting?

Rob,

After I left your house I started thinking about that odd fitting...I don't know if the threads are even the same as that of a standard 200bar DIN fitting. It makes me wonder if the reg was designed for some unique valve fitting similar to what some of the EU nitrox tanks currently wear.

Greg, I will tell you what. That is a good idea. I still need to locate a din tank to see if it even fits one. I was hoping that one of out European members would have something to say, but I guess this thing is even rare to them?
