The Applied System Technologies 70 Durometer Buna-N Nitrile O-Ring is made from a copolymer of Butadiene and Acrylonitrile. This material is highly resistant to petroleum-based oils and hydrocarbon fuels and can withstand temperatures ranging from -40°F to 250°F. These o-rings also have exceptional tensile strength and abrasion resistance properties. They perform well with most dilute acids, silicone oils, and lubricants as well as water applications.
