Yes, that confused me a little at first because I was looking for an OD and an ID.the one thing you have to keep, in mind is all metric Oring state the CS and ID
so in this case 2.5mm x 2 + 7mm ID and that give you 12mmOD
now if you take a 3.0mm and do the same thing you OD changes
now if change to inch sizes, the size you need falls in between a 108 and 109 one OD is too small and the other is too big
but again with the shins you can change the CS from 2.5mm nominal to 2.9mm and the ID and OD stay the same
now i said nominal and the reason is all Oring of the same size might not be the same size
the CS could be + or -
in most cases it will never make a difference but in this case where we are talking about 0.10mm it could
and to understand that better my paper i use in my printer is 0.10mm and that is 39 thousands
When all else fails I read the instructions
