Do any of you know off hand how small a section O Rings are available? I’ve just ordered some 1mm ID 1mm cross section O rings but they may be a bit too big in cross section.

I believe that 0.5 mm section is the smallest size have a look on simply bearings web site.

Pretty sure it was simply bearings I looked at, smallest was 1mm. I’ll check again.

The smallest standard size seems to be 1mm CS but I’ve found a specialist supplier that make miniature O rings. I’ve now found a supplier though that has O rings specifically for my needs. Not sure what size they actually are so I’m going to see if the ones I’ve ordered elsewhere fit first.

Thanks for the link GC. I’m sure they go down small enough and the prices look good although I’ve not checked the postage.
