Nitrile
NBR
Nitrile seals are highly versatile and widely used in various industries for their exceptional sealing capabilities. These seals, also known as Buna-N or NBR seals, are made from synthetic rubber composed of acrylonitrile and butadiene. Nitrile seals possess excellent resistance to oils, fuels, and other petroleum-based fluids, making them ideal for applications in automotive, aerospace, and hydraulic systems. Furthermore, their resilience against high temperatures and resistance to compression set ensure reliable performance even in challenging environments. Nitrile seals are also cost-effective, reliable, and easy to install, making them a popular choice in industries where efficient sealing is critical. Overall, with their impressive durability and broad compatibility, nitrile seals continue to be an essential component in various industrial settings.
Features and Benefits:
Nitrile (NBR) is one of the most commonly used elastomers for seals. This is because of the range of positive properties that it has. Such as, being able to withstand high temperatures. Nitrile (NBR) is able to maintain its core properties and shape when it is under high temperatures. As well as this, Nitrile also possess’ a high resistance to oils and fuels, this makes it very valuable for applications in the Oil & Gas industry and the Automotive industry.
Nitrile (NBR) is a highly durable material. It is able to withstand and perform well in harsh environments this is due to its great wear and tear resistance, this makes Nitrile (NBR) a great material to be used in applications that will need long-term performance. Even with its great wear and tear resistance Nitrile (NBR) is a very flexible material, this means that it can be machined or moulded into many different shapes and sizes. This level of flexibility means that Nitrile (NBR) is a brilliant choice for applications in a wide range of industries, such as: Automotive, Medical and Construction industries.
Industries:
Due to the great resistance that Nitrile (NBR) has against aviation oils and hydraulic fuels, it makes it a prime material to be used for sealing in this industry. Nitrile will most commonly be found in the manufacture of oil seals, gaskets and fuel hoses all being for the engines of aircraft’s. These will also be found in the construction of fluid handling systems. For more information on this industry click here or the heading above.
For similar reasons to the Aerospace industry, the Automotive industry will also rely Nitrile (NBR) for its great resistance to oils and fuels. Nitrile (NBR) is also an important material for this industry for its great temperature and durability resistance. Nitrile (NBR) is a component in most vehicle tires, it is also used a lot more on the inside of the vehicle, for components like fuel and oil systems, coolant hoses and the air intake hoses, as well as many other engine components.

Summary:
Great resistance to oils and fuels.
Very good elasticity at a range of temperatures.
Excellent temperature range of -40°C to 120°C.
Excellent resistance to abrasion (wear and tear).
Good shock and vibration absorption, reducing stress on other components.
Low compression set, meaning it will keep its form after being under pressure for an extended period time.
