Product Code:SAE AMS7274
Title:Rings, Sealing, Butadiene-Acrylonitrile (Nbr) Rubber Oil Resistant 65-75
Issuing Committee:Ams Ce Elastomers Committee
Scope: 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.
