What is an NBR O-ring - 80 Shore A?

An O-ring NBR 80 Shore A is a robust sealing element, ideal for applications that require extra strength and wear resistance. This O-ring, made of nitrile rubber, offers excellent resistance to oils, fuels, and various chemical substances, making it perfect for the automotive, aerospace, and industrial sectors.

Compared to an NBR O-ring with 70 Shore A, which is slightly softer and more flexible, the O-ringe NBR 80 Shore A provides more durability and higher pressure resistance. This makes it particularly suitable for applications where higher mechanical stress and less deformation are desired.

While a 70 Shore A O-ring has more adaptability to uneven surfaces, the O-ring NBR - 80 Shore A offers a longer lifespan and better performance in harsh conditions. Both types have their unique advantages depending on the specific needs of the application.

Properties of NBR 80

An O-ring NBR - 80 Shore A offers excellent properties for demanding applications. This O-ring, made of nitrile rubber, is highly resistant to oils, fuels, and various chemical substances. The hardness of 80 Shore A gives it a robust structure, making it better resistant to high pressure and mechanical stress compared to a 70 Shore A O-ring, which is softer and more flexible. This makes the 80 Shore A O-ring ideal for applications where durability and wear resistance are crucial.

In contrast to a 90 Shore A O-ring, which is even harder and stiffer, the O-ring NBR - 80 Shore A offers a better balance between rigidity and some flexibility. This makes it suitable for a wide range of industrial applications where both reliable sealing and a certain degree of adaptability are required.

The choice between these hardness grades depends on the specific requirements of the application, with a 70 Shore A O-ring being better for less demanding environments and a 90 Shore A for extreme conditions.

Advantages of an NBR O-ring in 80 Shore A

An O-ring NBR - 80 Shore A offers numerous advantages for industrial applications. This O-ring combines excellent resistance to oils, fuels, and chemical substances with a robust structure that can withstand high pressure and mechanical stresses.

Compared to a 70 Shore A O-ring, which is softer and more flexible, an 80 Shore A O-ring offers more durability and better pressure resistance, making it ideal for heavy-duty applications. On the other hand, a 90 Shore A O-ring is harder and stiffer, suitable for extremely high pressure and harsh conditions, but less flexible. The 80 Shore A O-ring forms an ideal middle ground, with a good balance between rigidity and flexibility, making it versatile.

These properties make an O-ring NBR - 80 Shore A a reliable choice for applications where both robustness and some degree of flexibility are required, such as in hydraulic systems, engines, and industrial machinery.

Applications of an NBR O-ring - 80 Shore A

An O-ring NBR - 80 Shore A is ideal for various applications that require a balance between rigidity and flexibility. It is widely used in hydraulic systems, engines, and industrial machinery due to its excellent resistance to oils, fuels, and chemical substances.

Compared to a 70 Shore A O-ring, which is softer and more flexible, an 80 Shore A O-ring offers higher pressure resistance and durability, making it suitable for heavier applications.

In contrast, a 90 Shore A O-ring is harder and stiffer, making it ideal for extremely high pressure and harsh conditions, but less flexible. The 80 Shore A O-ring offers an optimal middle ground, making it versatile for both demanding and less extreme conditions.

This versatility makes an O-ring NBR - 80 Shore A a reliable choice for industries that need both robust and flexible sealing solutions.

Specifications of an NBR O-ring - 80 Shore A

The O-ring NBR - 80 Shore A, with material number 108019001, has a hardness of 80 ±5 Shore A, a tensile strength of 14.9 MPa, and an elongation at break of 347%. The density is 1.30 g/cm³ and the durability at compression after 22 hours at 100°C is 11%.

After aging at 100°C in air, ASTM IRM oil 901 and 903, the hardness, tensile strength, elongation at break, and volume vary. For example, when exposed to air, the hardness increases by +2 points, while the tensile strength and elongation at break change by +3% and -10%, respectively.

In IRM oil 901, the hardness values remain almost unchanged, but the tensile strength and elongation at break decrease. The data of this O-ring NBR - 80 Shore A are obtained according to modern laboratory standards.
