What rubber material should be used for the O-rings and gaskets of the intake and exhaust valves in ammonia-hydrogen compressors?

Experts, what material should be used for the O-rings and gaskets of the intake and exhaust valves in ammonia-hydrogen compressors (primarily those using ammonia)? EPDM or perfluoroether?
For the O-rings and gaskets of the intake and exhaust valves in ammonia compressors, perfluoroelastomer materials that are resistant to corrosion and high temperatures should be used. Ammonia is a corrosive and toxic gas that can cause chemical reactions with rubber materials, leading to aging and cracking of such materials. Perfluoroelastomers, on the other hand, possess excellent resistance to chemical corrosion and high temperatures, making them suitable for use in the intake and exhaust valves of ammonia compressors. .
For a medium like ammonia, the rubber at the front is cheap but not suitable, while the one at the back may be suitable but is too expensive. I’ll check these days and find one that’s suitable.
