Recommended O-ring for Mares DIN first-stages?

[Archie Teuthis]

I had my new Mares Abyss/MR22 regulator converted to DIN. However, I neglected to ask about O-ring sizes for the first stage, and this is not covered in the manuals.

Do the Mares DIN first stages, including the MR22, take 122 (American) O-rings? 111? Another size?

Thanks in advance!

Archie,

Which Oring are you referring to. The external oring on the Din, that seats with the tank valve?

Zak,

Yes, that one! I am assuming a 112 (not 122 as I typed before) but would like to confirm it. To clarify, it's a new Abyss first-stage (I'm not sure if this is identical to the MR22 or not).

Archie,
Our service manual says ORing 115 Part # 46110117. I'm sure any lds will have the appropriate oring or they can simply order it from us using the 46110117 part #.
