Nitrile, also known as Buna-N o-rings, are made from a synthetic rubber material that is resistant to oils, fuels, and other chemicals. They are commonly used in a variety of industrial and automotive applications, such as sealing and lubrication. Nitrile o-rings have a high resistance to wear and tear and can withstand temperatures ranging from -40 to 250 degrees Fahrenheit. They are also known for their excellent compression set resistance, which means they retain their shape and seal after being compressed for long periods of time. Overall, nitrile is a cost-effective and durable option for applications that require resistance to chemicals and temperature extremes.
