Question La Spirotechnique Royal Mistral Orifice O ring info

[Erik22]

Hey Divers,

I have two spirotechnique royal mistrals. The seats are decent, those can be polished. What I am looking for is the o ring size that is on the removable volcano orifice. Unlike the USD mistrals, you can actually remove and replaced these as they wear out!

Does anyone happen to know that size of o ring?

Thanks,

Erik

You may find the attached service manual useful. It is in french but OC'red, so things can easily be translated. Maschine translations of the document don't look pretty as it is a scan, so you'd have to copy/paste translate.

The schematics specifies the O-Ring sizes in the R standard, which is french. Dimensions can easily referenced from sites like this.
