Try ebay for an 'O' ring set. You'll get a selectiob for very little money


You get a selection but often when you need one you find that they are
too thin. Although I have found a use for many in a set its always one
or two sizes that are used most.

Inside and outside diameter are the important parameters, assuming a
round cross section of the ring
