O-ring size on outside of regulator

[bvan]

I have a regulator I bought from AoA (not a Huma) in my FX Royale and the outside o-rings need replacing. Does anyone know what size these should be? From looking at the old ones they appear to be something like 2.5mm CS with a 12.5mm ID?

Any help on identifying these would be appreciated.

It is 2.4mm x 11.6mm for the genuine regulator

Thanks for the size info Snowbird.
