A general purpose, sulfur-cured Buna-N Nitrile O-Ring, the most commonly used elastomer for sealing products. Nitrile, also known as Buna-N or NBR, is a copolymer of Butadiene and Acrylonitirle. More than 50% of the Orings sold are Buna-N Nitrile Orings, commonly used in hydraulic/pneumatic motors, cylinders, pumps and valves.
