RE: Selection of Elastomer(material) for API682 seal

You can use EPDM which will be slightly less costly than the alternative, FFKM (perfluoroelastomer). If cost is not a concern, I would recommend Kalrez Spectrum 6375 for this application; I have several seals in this type of service with this grade of perfluoroelastomer and they perform well.

RE: Selection of Elastomer(material) for API682 seal

A safe bet for a refinery or other hydrocarbon processing facility is the perfluoroelastomer.  EPDM generally swells in the presence of hydrocarbon and can inhibit the movement of seal parts or squeeze brittle parts.
