The 70 Shore A hardness provides a perfect balance between flexibility and strength, meaning it can withstand both low and high pressure without deforming. This ensures a reliable seal and prevents leaks in demanding environments. Additionally, an NBR 70 O-ring has excellent wear resistance and durability, resulting in a longer lifespan and lower maintenance costs.
Its wide applicability and reliable performance make it a popular choice for applications where a durable and effective seal is crucial. Thanks to these properties, an O-ring NBR - 70 Shore A contributes to increased efficiency and reliability in various industrial processes.
An O-ring NBR - 70 Shore A is versatile and widely used in different industries. Its excellent resistance to oils, fuels, and chemical substances makes it ideal for the automotive industry, where it is used in engines, fuel systems, and hydraulic systems.
In the industrial sector, it is perfect for machines and equipment that operate under high pressure, thanks to its balance between flexibility and strength. Additionally, an NBR O-ring in 70 Shore A is suitable for applications in aerospace, where reliable seals are crucial under extreme conditions.
An O-ring NBR - 70 Shore A is also used in the food and beverage industry due to its good resistance to fats and oils. Its durability and wear resistance ensure a longer lifespan and less maintenance, increasing the efficiency and reliability of the systems in which it is used.
An O-ring NBR - 70 Shore A has some disadvantages that can be unfavorable in certain applications. Although an O-ring NBR - 70 Shore A offers a good balance between flexibility and strength, it may be less effective in very low-temperature conditions, where it can harden and lose its sealing properties.
Additionally, it is less resistant to ozone and weather influences, making it not ideal for outdoor applications without additional protection. In environments with very high temperatures above +120°C, it can degrade more quickly and lose its elasticity. Furthermore, a Nitrile O-ring in 70 Shore A may have limited resistance to certain aggressive chemicals, such as ketones and esters, limiting its usability in some chemical applications.
These disadvantages should be considered when selecting O-rings for specific industrial and technical applications. For applications where the O-rings are exposed to UV radiation, it would be better to choose EPDM O-rings. This is because these O-rings have better resistance to UV, water/moisture, and ozone.
The O-ring NBR - 70 Shore A, with material number 107019001, has various specific properties. The hardness is 70 ±5 IRHD, the tensile strength is 14.4 MPa, and the elongation at break is 389%. The density is 1.28 ±0.03 g/cm³. The compression set after 22 hours at 100°C is 11%.
At low temperatures, the material shows no cracks after 3 minutes at -40°C and has a TR10 value of -26.4°C. After aging at 100°C in air, ASTM IRM oil 901 and 903, and fuels A and B, the hardness varies between +3 and -11 points, while tensile strength, elongation at break, and volume also undergo significant changes.
This material complies with DVGW DIN EN 549 H3/B2 (-20...+80°C) standards. The data for this O-ring NBR - 70 Shore A are based on tests according to modern laboratory standards.
An O-ring NBR - 70 Shore A can be custom-made to meet specific needs and applications. Thanks to the adaptability of nitrile rubber, this O-ring can be manufactured in various sizes and shapes, making it ideal for unique industrial applications.
