O-Ring Size for Balloon Stem? EQ/Volcano

[zeebudz]

I need to make some new balloon bags for my Arizer Extreme EQ. My only existing balloon stem is using a rubber band and it is less than desirable, would like to do it correctly. Been searching and searching and cannot find any mention of the actual o ring size that is used for the stem. Anyone?

If I've found the right ones in my Arizer bag of bits - they're 10mm ID and about 1.7mm thick
10 x 2 is more common and easily found in different materials and colours so I'd probably go with the red or green 10 by 2s

Excellent - thanks so much for this info!
