O-ring 579x6 NBR

Main description

The O-Ring 579x6 NBR 70 Shore is a precision-manufactured industrial sealing ring designed for reliable static and dynamic sealing in demanding technical applications. Made from high-quality NBR (nitrile rubber) with a hardness of 70 Shore A, this O-Ring offers an optimal balance between elasticity, mechanical strength, and long-term sealing performance.

With an inner diameter of 579 mm and a cross-section of 6 mm, this rubber gasket is widely used in large-diameter sealing systems where dimensional stability and consistent compression are essential. NBR material provides excellent resistance to mineral oils, lubricants, fuels, hydraulic fluids, and greases, making this O-Ring suitable for hydraulic and pneumatic applications as well as general industrial sealing.

The O-Ring 579x6 NBR 70 Shore performs effectively as a static seal in flanges, covers, housings, and industrial equipment, while also being suitable for low-speed dynamic applications. Its material properties ensure low compression set, good abrasion resistance, and reliable sealing over extended operating cycles. This results in reduced maintenance intervals and improved system reliability in industrial environments.

Thanks to standardized dimensions and controlled hardness, this O-Ring integrates easily into existing designs and sealing grooves. It is commonly used in machinery, pumps, valves, industrial assemblies, and technical sealing components where high durability and chemical resistance are required. The product meets the expectations of engineers, maintenance departments, and procurement managers seeking dependable sealing solutions for professional use.
