Viton O-Ring Compounds exhibit excellent resistance to petroleum products, low compression set and high temperature resistance. 

The low temperature o-ring capability is somewhat restricted, however, in some cases the flow temperature sealing capability may be increased by specific design parameters. 

These materials meet the stringent Aerospace Specifications for o-rings AMS 7278, AMS 7279, and AMS 7280.  They are especially good for hard vacuum services and low gas permeability. 

The normal Viton o-ring temperature service range is:
 -200F to +4000F/ +4500F.
