本规范涵盖了航空和航天应用中O形圈、O形圈芯线、压缩密封件和就地模制垫圈形式的氟碳橡胶（FKM）。这些产品通常用作密封圈、压缩密封件、O形密封圈和与空气、各种燃料、润滑剂和特定液压流体接触的就地成型垫片，但用途不限于此。每个申请都应单独考虑。这类氟弹性体不建议用于高温稳定的“HTS”发动机机油。应单独评估每种“HTS”油。这种氟碳橡胶在空气中的典型使用温度范围为-20到+400-mDF（-29到+204-mDC）。

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.
