Buna-N O-Rings 70 Duro (NBR):

The most commonly used elastomer for sealing products. Nitrile, also known as Buna-N or NBR, is a copolymer of Butadiene and Acrylonitrile. It has a temperature range of -40F to +250F and is exceptionally resistant to petroleum-based oils and hydrocarbon fuels. Nitrile materials also exhibit excellent tensile strength and abrasion resistance properties. The material performs well with most dilute acids, silicone oils, and lubricants and in water applications. It is not recommended for use with ketones, aromatic hydrocarbons, and phosphate ester hydraulic fluids.
