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.

- Round, mechanical gasket designed to be seated in a groove and compressed during assembly between two or more parts, creating a seal at the interface
- One of the most common types of seals because they are inexpensive, reliable and have simple mounting requirements
- May be used in static applications, where little range of motion is required or used in dynamic applications such as rotating pump shafts and hydraulic cylinder positions
- Sulfur-Cured
- 15 years shelf life
