Material Characteristics and Performance
The O-ring 350x3 NBR 70 ShA is a precision-made sealing ring manufactured from nitrile rubber (NBR) with a hardness of 70 Shore A. NBR is one of the most widely used elastomers in technical sealing applications, especially where oils, greases, hydraulic fluids, fuels, and water are present.
The 70 ShA hardness provides an optimal balance between elasticity and dimensional stability, ensuring reliable sealing performance in both static and moderate dynamic conditions. This Oring is suitable for industrial environments where durability and repeatability are required.
Applications in Hydraulics, Pneumatics, and Machinery
The O-ring 350x3 NBR 70 ShA is designed for use in hydraulic cylinders, pneumatic systems, valves, pumps, industrial equipment, flange connections, and housing assemblies. It is widely adopted across machine manufacturing, automotive, agricultural, and maintenance sectors.
The material maintains stability over a temperature range of approx. -30°C to +100°C and offers good wear resistance, making it a dependable choice for long-term service operations.
