HW90 RX1 Oring size needed

[Scrinja]

Hi guys thanks for having me
Im looking for the Oring size for the Inertia weight if anyone can help
There is alot of info on the net in imperial measurements alas ie this waffle on the
BBS UK ForumThanks DaveI have now come across a reference that gives them as a BS116 ... 15/16 od x 3/32 cs(3/4" id)Confusing isn't it?
Weihrauch dont do Imperial specs they are all Metric in Germany
I have the correct size for the upper 2 Orings which are 23mm x 2.5mm
I had the Inertia piston sizes but like a dummy i have lost them
If anyone could help i would be really grateful
Thanks guys
