O-Ring 65x1,5 NBR 70 ShA

Applications in Hydraulic and Pneumatic Systems

The O-Ring 65x1,5 NBR 70 ShA is a precision rubber gasket designed for static sealing in industrial systems. This industrial sealing ring is widely used in hydraulic and pneumatic applications, pipe connections, flanges, valves, and machinery components where reliable tightness is required.

The size 65x1,5 means 65 mm inner diameter and 1,5 mm cross-section, ensuring accurate fit in standard sealing grooves. Proper compression inside the housing guarantees an effective static seal, preventing leakage of oil, grease, air, and other operating media.

NBR 70 ShA Material - High Durability and Oil Resistance

Manufactured from NBR (nitrile butadiene rubber) with hardness 70 ShA, this O-Ring offers high durability and excellent resistance to oils and grease. NBR is one of the most commonly used elastomers in industrial sealing due to its balanced mechanical strength, elasticity, and cost efficiency.

The typical operating temperature range for NBR is approximately -30°C to +100°C, making it suitable for a wide range of industrial environments. Its chemical resistance and stable physical properties ensure long service life in demanding conditions.

Reliable Static Sealing Performance

The O-Ring 65x1,5 NBR 70 ShA is primarily intended for static sealing applications where there is no relative movement between components. When properly installed, it creates uniform pressure distribution and ensures tight, long-term sealing performance.

It is commonly used in industrial equipment, hydraulic assemblies, pneumatic systems, and maintenance operations where reliable technical sealing components are essential.
