Cleaning up the fuel cap on the BOB the Blue Old Bike.

The O ring near the top of the lock is old and hard. Not a lot of sealing happening there, hence the dirty and binding innards. (Now clean and free.)
Fuel lock O ring size Lock210
I presume same as the one on this luggage lock.

Does anyone know the correct size of the O ring? The ones I have in my selection box appear too thin or too thick, so no better seal or would bind too much.

Don't want to cut the old one out until I have a correct replacement.

Thanks,

Bill

A bit of a long shot, try a locksmith.

O-ring size is i.d. X thickness.

Measure the width of the groove and multiply by 2.  Subtract that from the o.d. of the ring. 

That should get you in the ballpark.  Get a couple in the next size up and down from what you measured.

I just measured one of the locks I have here and it looks like 13mm x 2mm.
