Nitrile Rubber Gaskets

Nitrile rubber gaskets, also known as NBR (Nitrile Butadiene Rubber) gaskets, are widely used sealing components known for their excellent resistance to oil, fuel, and other hydrocarbon-based fluids. They are commonly used in various industries for sealing applications where resistance to oils, fuels, and solvents is critical. Here are some key features and applications of nitrile rubber gaskets:

  1. Oil and Fuel Resistance: One of the primary advantages of nitrile rubber gaskets is their exceptional resistance to oil, fuel, and grease. This makes them ideal for sealing applications in automotive, marine, aerospace, and industrial equipment where exposure to petroleum-based fluids is common.

  2. Chemical Resistance: Nitrile rubber gaskets also exhibit good resistance to a wide range of chemicals, including acids, alkalis, and hydraulic fluids. This versatility makes them suitable for sealing applications in various chemical processing, manufacturing, and engineering industries.

  3. Temperature Resistance: Nitrile rubber gaskets can withstand moderate temperatures ranging from -40°C to 120°C (-40°F to 248°F), making them suitable for use in both low and high-temperature environments. Special formulations may extend this temperature range further.

  4. Compression Set Resistance: Nitrile rubber gaskets have good compression set resistance, meaning they can maintain their original shape and sealing properties even after being subjected to compression over time. This ensures long-term sealing performance and reliability.

  5. Flexibility and Conformability: Nitrile rubber is known for its flexibility and resilience, allowing NBR gaskets to conform to irregular surfaces and provide effective sealing in various applications, including flanges, pipes, valves, and machinery.

  6. Water Resistance: While nitrile rubber gaskets are not as inherently resistant to water and steam as some other elastomers like EPDM, they still offer reasonable water resistance, especially in combination with appropriate sealing techniques.

  7. Cost-Effectiveness: Nitrile rubber gaskets are generally cost-effective compared to some other elastomeric materials, making them a popular choice for sealing applications where budget considerations are important.

  8. Customization: Nitrile rubber gaskets are available in various shapes, sizes, and thicknesses to suit different sealing requirements. They can be customized to meet specific application needs, including custom gasket profiles and dimensions.

Nitrile rubber gaskets find widespread use in automotive engines, hydraulic systems, oil and gas equipment, pumps, compressors, and a variety of industrial machinery where reliable sealing against oils, fuels, and chemicals is essential.
