Rubber, Butadiene-Acrylonitrile (NBR), 65 to 75 Hardness, For Elastomeric Seals in Aircraft Engine Oil Systems
This specification covers a butadiene-acrylonitrile (NBR) rubber in the form of molded rings. These rings have been used typically for sealing at temperatures as low as -55 degrees C (-67 degrees F) where resistance to hot petroleum-base lubricating oil is required, but usage is not limited to such applications.
AMS7274J results from a Five Year Review and update of this specification. Qualification requirements have been added.
