This specification covers a fluorocarbon (FKM) rubber in the form of O-rings, O-ring cord, compression seals and molded-in-place gaskets.

These products have been used typically as sealing rings, compression seals, and molded-in-place gaskets in contact with air and a wide variety of fuels, lubricants, and specific hydraulic fluids from -29 to +260 degrees C (-200 to +500 degrees F), but usage is not limited to such application, each application however should be considered individually. This class of fluoroelastomers is not recommended for use in high temperature stabilized, "HTS", engine oils. Each "HTS" oil should be evaluated separately.
