Oring 100x3 NBR 70 ShA

Main Description

The Oring 100x3 mm NBR 70 ShA is a precision technical sealing element made of nitrile rubber, designed for reliable sealing in hydraulic, pneumatic, and industrial systems exposed to oils and fuels.

This NBR O-ring with an inner diameter of 100 mm and a cross section of 3 mm is part of one of the most widely used dimensional groups in industrial sealing applications. The 70 ShA hardness provides an optimal balance between flexibility and mechanical strength, ensuring consistent sealing performance in both static and dynamic conditions.

Within the technical sealing category of NBR O-rings, the 100x3 mm size is commonly selected for medium-duty industrial applications where durability, chemical resistance, and cost efficiency are essential. NBR material is highly resistant to mineral oils, greases, and fuels, making it a standard choice in industrial maintenance and production systems.
