Nitrile o-rings, which are also commonly referred to as NBR o-rings and Buna-N o-rings, are currently the most popular type of o-ring compound used in various applications today. This widespread preference can be attributed to their low cost, as well as their good mechanical performance. Nitrile o-rings exhibit effective resistance to water, most basic oils, and lubricants, along with a limited range of fuels, making them suitable for many pneumatic and hydraulic systems. They are often regarded as the default choice for a variety of basic applications due to their versatility. However, it is important to note that these o-rings are not recommended for exposure to sunlight, UV light, ozone, and general outdoor weathering. Additionally, they should not come into contact with harsh chemicals, acids, ketones, and many other substances that could compromise their integrity.
