Product Code:SAE AMS3212
Title:Acrylonitrile Butadiene (Nbr) Rubber, Aromatic Fuel Resistant, 55-65
Issuing Committee:Ams Ce Elastomers Committee
Scope:This specification covers a nitrile (NBR) rubber in the form of sheet, strip, tubing, extrusions, and molded shapes. These products have been used typically for parts, such as gaskets, diaphragms, bushings, grommets, and sleeves, requiring resistance to aromatic and aliphatic fuels when continuously or alternately exposed to both, but usage is not limited to such applications.
