Product Code:SAE AMS7258
Title:Rings, Sealing, Butadiene-Acrylonitrile (Nbr) Rubber Fuel Resistant, Low Shrinkage 65-75
Issuing Committee:Ams Ce Elastomers Committee
Scope: This specification covers butadiene acrylonitrile (NBR) rubber in the form of molded rings. Primarily for use in aircraft fuel systems operating from -55 degrees to +125 degrees C (-67 degrees +257 degrees F). These rings contain less plasticizer than normally used in aircraft fuel seals; therefore, there is less shrinkage when the rings are dried out.
