O-ring size

[mikemi]

I know it has been posted in the forum before, but I have searched for the last two hours and have not been lucky enough to find the answer to my question. What are the od and id dimensions of the o-ring on the Board Tracking Endoder?
I can't find the size listed in the parts manual anywhere.

Mike :confused:
