So simple anyone can do it
Probably the fastest and easiest way to correct identity a o-ring

LOOKS INTIMIDATING, BUT EASY TO USE
SHOULD INCLUDE INSTRUCTIONS. DOES ITS JOB SORTING ORINGS. HARD TO READ. WOULD BE NICE IF THE NUMBERS WERE PAINTED OR MORE VISIBLE

It Could Be Better...
Yes, it does work. I tried it with several known O-rings and it sized them correctly. HOWEVER, the price for this piece of plastic is excessively high, it is not finished very well (mould markings left on), absolutely no attempt to make the size numbers more readable, and No Instructions. For the price we are paying for this big piece of plastic, would it be that difficult to include some basic instructions?
