Basic Info.:

Materials:

We usually make the o-ring flat washers / gaskets with NBR (Nitrile Rubber), Silicone, EPDM and so forth.

Of course after you choose the material, then you should choose the hardness,

NBR, from 30 Shore A to 95 Shore A.

Silicone, from 25 Shore A to 85 Shore A

EPDM, from 30 Shore A to 95 Shore A.

Tolerance is -/+5 shore, so every 5 shore a is a grade. That is to say, when you need a hardness 70 Shore A, then the hardness from 65 shore A to 75 Shore A is normal. Of course, if you have high requirements about hardness, then we can make the tolerance between -3 Shore A to +3 Shore A.
