RGS Clutch Slave Cylinder O Ring?

[Kiwi Laverda]

Been reading some posts on this and it appears there are 30 & 31mm slave cylinders.
Not taken mine off as yet but does anyone have the spec for the O rings?

take your sample to Seal Imports Ltd in ChCh - never found a size or section yet they can't supply.

If you are using Dot 4 Fluid the 'O' ring is usually EPDM.
