What are NBR O-rings - 90 Shore A?

NBR O-rings - 90 Shore A are extremely robust sealing elements, specially designed for applications that require maximum pressure and wear resistance. Made of nitrile rubber, these O-rings offer excellent resistance to oils, fuels, and various chemical substances, making them perfect for the most demanding industrial conditions.

Compared to NBR 70 Shore A O-rings, which are softer and more flexible, NBR O-rings - 90 Shore A offer significantly more rigidity and less deformation under high pressure. This makes them less suitable for applications where flexibility and adaptability are essential, but ideal for environments where maximum durability and pressure resistance are required.

70 Shore A O-rings are better suited for lower pressure applications where a higher degree of flexibility is needed, while NBR 90 O-rings perform best in highly demanding and heavy industrial applications. If you are looking for more information about NBR O-rings - 70 Shore A, click here.

Properties of NBR 90 O-rings

NBR O-rings - 90 Shore A offer exceptional strength and durability, ideal for heavy-duty applications. These O-rings, made of nitrile rubber, are particularly resistant to oils, fuels, and various chemical substances. They are designed to withstand high pressure and extreme mechanical stress without deformation, making them perfect for demanding industrial environments.

Compared to NBR 70 Shore A O-rings, which are much softer and more flexible, the 90 Shore A O-rings offer significantly more stability and less elasticity. This makes 70 Shore A O-rings better suited for applications where adaptability to uneven surfaces and lower pressure is required.

In contrast, NBR O-rings - 90 Shore A are ideal for situations where maximum pressure resistance and minimal deformation are crucial. These properties make an NBR 90 O-ring a reliable choice for heavy industrial applications.

Applications of NBR O-rings - 90 Shore A

NBR O-rings - 90 Shore A are ideal for applications that require maximum pressure and wear resistance. They are widely used in heavy industrial environments such as hydraulic systems, pumps, and engines, where high pressure and mechanical stress are present. Thanks to their robust construction, they offer excellent resistance to oils, fuels, and chemical substances.

Compared to NBR 70 Shore A O-rings, which are softer and more flexible, 90 Shore A O-rings are less suitable for applications where adaptability and elasticity are needed, such as in low-pressure systems and equipment with uneven sealing surfaces. 70 Shore A O-rings are better suited for applications requiring more flexibility and adaptability, such as in vacuum systems and less demanding mechanical environments.

The choice between 70 and 90 Shore A O-rings depends on the specific requirements of the application, with NBR O-rings - 90 Shore A being preferred in highly demanding and heavy-duty conditions.

Advantages of NBR 90 Shore A O-rings

NBR O-rings - 90 Shore A offer numerous advantages for demanding industrial applications. Thanks to their exceptional pressure and wear resistance, they are ideal for use in harsh conditions such as hydraulic systems, pumps, and engines. These O-rings, made of nitrile rubber, offer excellent resistance to oils, fuels, and chemical substances, enhancing their durability and reliability.

The high hardness of 90 Shore A ensures that they deform less under high pressure and mechanical stress, leading to a longer lifespan and less maintenance. Additionally, they retain their sealing properties even in extreme conditions, making them a reliable choice for critical applications.

This robustness makes them superior to softer variants, such as 70 Shore A O-rings, which, while more flexible, are less pressure-resistant. Therefore, NBR O-rings - 90 Shore A offer an optimal solution for industrial environments requiring maximum performance and durability.

Applications of NBR O-rings - 90 Shore A

NBR O-rings - 90 Shore A are ideal for applications that require maximum pressure and wear resistance. They are extensively used in heavy industrial environments such as hydraulic systems, pumps, and engines, where high pressure and mechanical stress are present. Thanks to their robust construction, these O-rings offer excellent resistance to oils, fuels, and various chemical substances, enhancing their durability and reliability.

They are also suitable for use in the aerospace and automotive industries, where reliable seals are crucial under extreme conditions. Additionally, they are used in compressors and heavy machinery due to their ability to withstand high pressure and stress without deformation.

These properties make NBR O-rings - 90 Shore A a reliable choice for applications where maximum strength and long-term performance are essential. Their high hardness ensures that they deform less, resulting in a longer lifespan and less maintenance, thus improving the efficiency and reliability of the systems in which they are used.

Disadvantages of an NBR 90 O-ring

NBR O-rings - 90 Shore A have some disadvantages that limit their usability in certain applications. Due to their high hardness, they are less flexible and have difficulty adapting to uneven surfaces, which can lead to less effective seals at low pressure.

This makes them less suitable for applications where adaptability and elasticity are important. Compared to NBR 70 Shore A O-rings, which are much softer and more flexible, the 90 Shore A O-rings offer less adaptability and can fail more quickly in situations where surface variations occur. 70 Shore A O-rings are better suited for lower pressure applications and environments where flexibility is essential, such as in vacuum systems and delicate equipment.

Moreover, due to their stiffness, NBR O-rings - 90 Shore A can wear out faster when subjected to dynamic movements or vibrations, leading to more frequent replacement and higher maintenance costs. Therefore, they are most suitable for static seals in heavy industrial applications.

Specifications of NBR O-rings - 90 Shore A

NBR O-rings - 90 Shore A, with material number 109019001, have a hardness of 90 ±5 Shore A, a tensile strength of 18.9 MPa, and an elongation at break of 196%. The density is 1.30 ±0.05 g/cm³. The durability at compression after 22 hours at 100°C is 10%.

The low temperature resistance of NBR O-rings - 90 Shore A, measured as TR10, is -20°C. After aging at 100°C in air and ASTM IRM oil 901 and 903, the properties vary: the hardness changes by +1 to -3 points, the tensile strength by +4 to +7%, the elongation at break by -3% to +2%, and the volume by -4% to +7%.

These data are obtained according to modern laboratory standards and may vary in measurements on finished products.
