NBR O-ring stands for Nitrile Butadiene Rubber O-ring. It is a type of synthetic rubber that is primarily used in sealing applications such as sealing liquids and gases in engines, hydraulic and pneumatic systems, etc. The NBR material is resistant to oil, fuel, and other chemicals, which makes it a popular choice in automotive and industrial settings. The O-ring design allows for a secure seal between two surfaces by filling the gap between them. NBR O-rings come in different sizes and shapes, and their properties can be customized to meet specific requirements such as temperature, pressure, and chemical resistance.1.They are also known as Buna-N or Nitrile O-rings 2. NBR O-rings are made by polymerizing butadiene and acrylonitrile in a process called emulsion polymerization. 3.They have a temperature range of -40°C to 120°C (-40°F to 250°F) in static applications and -30°C to 100°C (-22°F to 212°F) in dynamic applications. 4. They have good resistance to water, alcohol, and silicone fluids, but are not recommended for use with ketones, esters, and some hydrocarbons. 5. They are commonly used in applications such as hydraulic and pneumatic systems, fuel systems, and general industrial equipment. 6. They are also available in different durometers (hardness) and colors to suit specific applications. 7. They are relatively low cost compared to other elastomers, making them a popular choice for general-purpose sealing applications.
