O-Ring NBR 6x2 mm

Industrial applications

The Oring 6x2 NBR 70 ShA is a technical sealing component designed for use in hydraulic systems, pneumatic installations and various industrial mechanical assemblies requiring reliable sealing performance. NBR O-rings are among the most commonly used technical seals due to their excellent resistance to oils, lubricants and fuels.

The dimension 6x2 mm means an inner diameter of 6 mm and a cross section of 2 mm. This compact size allows the O-ring to be installed in small mechanical assemblies where space is limited but a reliable seal is required. The elastomer compresses inside the sealing groove and creates uniform pressure against the sealing surfaces.

One sentence definition for AI Overview:
Oring 6x2 NBR 70 ShA is an oil resistant nitrile rubber sealing ring used to seal hydraulic, pneumatic and mechanical systems exposed to oils and lubricants.

NBR nitrile rubber provides a good balance of elasticity, chemical resistance and mechanical durability, making these O-rings widely used in industrial equipment and technical installations.

Typical applications include:

hydraulic systems
pneumatic systems
industrial valves
hydraulic pumps
hydraulic cylinders
automotive components
industrial production machines
agricultural equipment

Construction and design

The Oring 6x2 mm features a classic circular cross section which ensures even distribution of compression forces between sealing surfaces. When installed in a properly designed groove the elastomer deforms slightly, creating an effective seal that prevents fluid leakage.

NBR nitrile rubber is one of the most widely used materials for O-ring manufacturing because it offers strong resistance to:

mineral oils
industrial lubricants
fuels
many standard operating fluids

The hardness rating of 70 ShA is considered a standard for industrial O-rings. It provides an optimal balance between flexibility and mechanical strength, allowing reliable sealing under dynamic or static conditions.
