This specification should not be used to address products such as O-rings, compression seals, O-ring cord, and molded-in-place gaskets. For those applications AMS7379 should be used.
These products have resistance to a variety of gas turbine engine oils, including high thermal stability (HTS) oils, fuels, and hydraulic fluids, but usage is not limited to such applications. Each application should be considered separately. This fluorocarbon (FKM) has a service temperature range of -60 to +400°F (-51 to +204°C) in air.
