Nitrile rubber (NBR) o-rings, also known as Buna-N, are one of the most commonly used sealing elastomers due to resistance to petroleum-based fuels and lubricants and its relatively low price. Standard Nitrile o-rings are usually sulfur-cured. Sulfur-cured compounds offer better low-temperature properties but are more prone to hardening with high temperatures. Performs well in Petroleum-based oils and fuels, Aliphatic hydrocarbons, Vegetable oils, Silicone oils and greases, Ethylene glycol, Dilute acids.Does not perform well in Aromatic hydrocarbons, Automotive brake fluid, Chlorinated hydrocarbons, Ketones, Ethers, Esters, Phosphate ester hydraulic fluids, Strong acids, Ozone, weathering, and sunlight.
