If you do some exact measurements: ID, OD, and section width, you should be able to zero in on the right size here: McMaster Carr

It seems I'm looking for a nonstandard size (possibly metric) as it is smaller than the 1/16" diameter.

I have a Moprod "Motor Products" clutch slave cylinder - basically a copy of the Mini clutch slave cylinder in aluminium.  They were available some 30+ years ago. The part number cast on the bottom is 424700 and the repair kit is a 424700R.  Some of the repair kits come with either two or three parts.  I have one of the kits here in front of me, just need the o-ring.

What I am looking for is a source for the o-ring on the right in the picture ( #30 0-ring shown on the left - 7/8" o.d. x 3/4" i.d. x 1/16" ).
Seems to be very similar except for the smaller diameter.  Not found at Lowe's, Home Depot, or ACE.
