Espace 1.9 DCI throttle body O ring size?

Hi all,

Does anyone know the size of the o ring that fits behing the throttle body to create a seal?

i will be taking it off on friday as i believe it has failed.

I work in a silicone factory so if i can find out the size i can make one for free.

cheers all :d
