If you convert, make sure you get the 300bar DIN.
You'll need a 1" socket and torque wrench to do the conversion - these can be hard to source. A mistake can damage the 1st stage. Especially the threads, which are dissimular hardness metals. If you have any doubts, let a SP service tech do the actual conversion.
I don't think SP even sells the 200 bar fitting any more, at least I haven't seen one in a while. You don't really need the 1" modified socket; you need it to install the yoke retainer, but for removal you can use a big adjustable wrench or even a vice to hold the yoke nut and just spin the reg off. It'll be a bit of a tug.
You do need the allen wrench socket and torque wrench to install the DIN.
