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.
