O-Ring 123,2x6,99 NBR 90 ShA

NBR 90 ShA O Ring for High-Pressure Industrial Applications

High Resistance to Oils, Compression and Mechanical Load

Technical Data and Use in Hydraulic Systems

Main Description:
The O Ring 123,2x6,99 NBR 90 ShA is a professional sealing ring designed for demanding industrial environments where increased hardness and pressure resistance are required. Manufactured from nitrile rubber (NBR) with a hardness of 90 ShA, this rubber gasket provides enhanced resistance to extrusion, deformation and mechanical stress.

With an inner diameter of 123,2 mm and a cross-section of 6,99 mm, this O ring is commonly used in large hydraulic assemblies, industrial cylinders and heavy-duty equipment. As a technical seal, it ensures reliable static sealing and can also be applied in selected low-speed dynamic applications.

NBR material offers high resistance to oils and grease, making this O ring suitable for hydraulic and pneumatic systems exposed to mineral oils, lubricants and fuels. The increased hardness of 90 ShA is particularly recommended for high-pressure environments, where standard 70 ShA sealing solutions may not provide sufficient stability.

The precision-molded cross-section guarantees uniform compression within the groove, minimizing leakage risk and maintaining consistent sealing performance. This sealing ring is widely used in industrial applications, including hydraulic presses, pumps, agricultural machinery and heavy equipment requiring robust and durable sealing components.

For B2B buyers, maintenance departments and technical wholesalers, the 123,2x6,99 NBR 90 ShA O ring represents a reliable solution that combines dimensional accuracy, high durability and long service life in continuous operation.
