A Micrometer, plenty on ebay, an example of a cheap one:

You need to measure the diameter of the rubber the 'O' rings are made of and the overall diameter.

If the 'O' rings are only lasting a few weeks then something is wrong with the design ?

It will be a standard size, so lay the o ring on a rule, and take the outside diameter and thickness of the ring. Then check the sizes on Google or your supplier.

If you have a vernier gauge to measure, it may make things easier.
