SAE AMS7259E

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

These products have been used typically as sealing rings, compression seals, O-ring cord, and molded-in-place gaskets in contact with air and a wide variety of fuels, lubricants, and specific hydraulic fluids from but usage is not limited to such application. Each application 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. This fluorocarbon rubber has a typical service temperature range of -20 to +400 \mDF (-29 to +204 \mDC) in air.
