Mares 82x 1st stage O-rings

[KvdE]

Hi,

Currently I'm trying to build a save-a-dive kit for the equipment I have myself, before the diving season starts.
At the moment I'm struggling to find the right O-ring size for in between the tank valve and the 1st stage of the DIN version of the Mares 82x.

I contacted 2 dive shops and unfortunatly got two different Mares part numbers.
The first one was part number 46110247, a 10.77mm x 2.62mm 70sh O-ring (specs from their website), which sounds odd to me because it's at the high pressure side (and therefore I would expect 90sh hardness for the O-ring).
The second part number was 46110227, I couldn't find specifications of this one.

So now I got two different part numbers, but I don't know which is the right one. I tried to find a exploded view with part numbers or a service manual of the 82x 1st stage so I could check the part number myself, but I could only find old service manuals from long before the 82x was introduced.
Does someone know which one is the right one, or does somebody have a recent service manual/exploded view of the 82x so I can have a look myself?

Kind regards,
Koen

Scubagaskets.com seems to list 46110247 in both 70sh and 90sh versions, but the url and the product page seem to differ for the 90sh (the 90sh url has 46110108 but specifies 46110247 on the product page)
