O-Ring 12mm x 3mm High ACN Nitrile 70 ShA Black -25°C to +150°C

High ACN Nitrile is a Copolymer of acrylonitrile and butadiene with a high ACN content of >45%. NBR materials typically provide excellent resistance to petroleum-based oils, fuels and greases, as well as, very low gas permeability, ozone resistance, plus exceptional heat ageing and mechanical properties. This material combines the excellent mechanical properties and wear resistance of nitrile with enhanced resistance to high temperatures and chemical exposure. High ACN Nitrile is particularly suited for sealing applications where extreme chemical resistance, excellent sealing performance, and high mechanical strength are essential.
