O-Ring 574.00mm x 5.33mm nitrile-nbr-9237 70 ShA black -30°C to +100°C

Nitrile (NBR) is a popular material for O-rings due to its excellent resistance to oils, fuels, and other chemicals, making it ideal for automotive, industrial, and fluid sealing applications. The material offers good mechanical properties, including high tensile strength and resilience, and performs well in a wide range of temperatures. However, NBR has some limitations; it is prone to degradation when exposed to ozone, weathering, and high temperatures, which can cause it to become brittle over time. Additionally, NBR has limited resistance to certain chemicals, such as ketones and esters, and may not be suitable for environments with extreme chemical exposure or very high-temperature conditions. Despite these cons, its cost-effectiveness and broad chemical compatibility make NBR O-rings a commonly used choice in various sealing applications.
