Advantage Good Oil and Fuel Resistance Heat and Low Temperature Resistance Vapour Resistance

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.
