O-rings, in fluorocarbon rubber (FKM), low compression set. Hardness 80 IRHD1 Scope This standard specifies the characteristics of o rings in fluorocarbon rubber FKM, low compression set, hardness 80 IRHD, for aerospace applications. They are intended to be used in air, mineral synthetic oil and fuel systems. Operating conditions Temperature: Continuous operation: 20 C to + 225 C; Static applications minimum temperature of use: 50 C. Limitation: not to be used with phosphoric ester type hydraulic fluids (permanent or
