Buna-N (Nitrile) O-rings are the most widely used for sealing applications. They effectively resist petroleum-based oils, hydraulic fluids, most silicone fluids, and nonaromatic fuels. They resist taking a set after being compressed; they have high tensile strength, and high abrasion resistance. Buna-N is not compatible with phosphate esters, ketones, or brake fluids, strong acids, and ozone. Durometer is Shore A: 70; temperature range is -65 to +225/250F. | |
