NBR (nitrile butadiene rubber) O-rings with a hardness of 88-90 Shore A (Sh) are extremely hard seals, ideal for applications requiring high mechanical resistance and tight sealing. These O-rings are particularly suitable for industrial and mechanical environments where increased hardness and enhanced wear resistance are beneficial.
NBR material provides outstanding resistance to oils, greases, and fuels, making it an ideal choice for applications involving frequent contact with lubricants or fuels.
With a hardness of 88-90 Sh, these O-rings offer exceptional mechanical strength, enhancing wear resistance and extending service life, especially in high-pressure or intensive-use systems.
Although higher hardness reduces flexibility, NBR 88-90 Sh O-rings ensure tight sealing and dependable performance, particularly in applications where durability and reliability are crucial.
NBR O-rings effectively operate within a temperature range of -30°C to +100°C, adapting to various thermal environments.
