O-Ring 582.68x5.33 NBR 70Shore

Material properties and sealing performance

The O-Ring 582.68x5.33 NBR 70Shore is a precision-engineered industrial sealing ring designed for reliable static sealing in large-diameter applications. Manufactured from NBR (nitrile butadiene rubber), this O-ring offers excellent resistance to mineral oil based oils, greases and standard hydraulic fluids, making it one of the most widely specified rubber sealing materials worldwide.

With an inner diameter of 582.68 mm and a cross-section of 5.33 mm, this O-ring is intended for large sealing grooves where dimensional accuracy, uniform compression and long-term stability are essential. The 70 Shore hardness provides an optimal balance between elasticity and mechanical strength, ensuring consistent sealing pressure without excessive compression set.

Industrial applications

The 582.68x5.33 NBR O-Ring is commonly used in hydraulic and pneumatic applications, heavy industrial machinery, pumps, valves, flanges and large housings. It performs reliably in contact with mineral oil based lubricants, aliphatic hydrocarbons and common industrial media, making it a trusted rubber gasket for general industrial sealing.

This O-ring is primarily designed as a static seal, suitable for fixed joints and flanged connections where reliable sealing and long service life are required. Its material properties allow it to maintain sealing performance under continuous mechanical load and variable operating conditions.

Advantages for B2B customers

For B2B users, the O-Ring 582.68x5.33 NBR 70Shore offers high durability, predictable performance and cost efficiency. NBR rubber provides proven resistance to oils and mechanical wear, reducing the risk of leakage and minimizing maintenance intervals. The standardized dimensions support easy integration into existing sealing designs, making this O-ring a practical choice for OEM production, maintenance and industrial procurement.

Main product description

The O-Ring 582.68x5.33 NBR 70Shore is a professional rubber seal developed for demanding industrial sealing applications. As a technical sealing component, it delivers reliable performance through controlled compression, stable material properties and resistance to common industrial fluids.

NBR is a copolymer of butadiene and acrylonitrile, engineered to provide strong oil resistance while maintaining flexibility across a typical operating temperature range of -30°C to +100°C, with short-term exposure up to +120°C. The 70Shore hardness ensures a stable sealing interface, low deformation under load and consistent sealing force over extended service periods.

This industrial sealing ring is suitable for new installations as well as maintenance and replacement tasks in large mechanical systems. It is widely specified by engineers and procurement managers seeking dependable rubber sealing solutions for hydraulic, pneumatic and general engineering applications.
