SAE AMSP5315C PDF
This specification covers an acrylonitrile-butadiene (NBR) rubber in the form of molded rings, molded compression seals, molded O-ring cord, and molded-in-place gaskets for aeronautical and aerospace applications.
These products have been used typically at temperatures from -65 °F (-54 °C) to +180 °F (+82 °C) where resistance to fuel is required, but usage is not limited to such applications. Each application should be considered individually. It is the responsibility of the user to determine that this specification is appropriate for the environments (temperature range, fluids exposure, etc.) in which it is sought to be used.
