O rings

Do any of you experts know the size of the o rings for the boro tank. I know you can buy a repair kit, but was wondering about buying some o rings.

9mm id, measuring one of the spares.

You usually need 2 measurements to order o-rings, the OD and the thickness.
Using the spares I have, my gauge says 12mm x 1.5mm, making the ID 9mm as @MavicP says

Cheers both, useless at measuring those things
