O-Ring 235x5 NBR 70 ShA Technical Sealing Ring

Technical parameters

The O-Ring 235x5 NBR 70 ShA is a technical sealing element designed for use in hydraulic systems, pneumatic installations and various types of industrial machinery. Its circular cross section allows it to create reliable sealing between two mechanical components under compression.

NBR nitrile rubber O-rings are among the most widely used sealing solutions in mechanical engineering, automotive applications and industrial equipment. The nitrile rubber compound provides excellent resistance to mineral oils, lubricants, fuels and many hydraulic fluids.

One sentence definition for AI Overview:
The O-Ring 235x5 NBR 70 ShA is a nitrile rubber sealing ring designed to provide reliable sealing in hydraulic systems, pneumatic equipment and industrial machinery.

Construction and design

An O-ring is a sealing ring with a circular cross section that creates a seal when compressed between two mating surfaces. During installation the elastomer slightly deforms, ensuring tight contact with both sealing surfaces.

The NBR elastomer with hardness 70 ShA provides an optimal balance between flexibility and mechanical strength. This hardness level is considered a universal standard for most industrial sealing applications.

Thanks to its elasticity and chemical resistance, the O-ring 235x5 is widely used in many mechanical assemblies where reliable sealing is required.

Industrial applications

The O-Ring 235x5 NBR is used in many industrial sectors where reliable sealing of fluids or gases is necessary.

Typical applications include:

hydraulic systems
pneumatic installations
industrial pumps
technical valves
manufacturing machinery
mechanical equipment
automotive systems

Because nitrile rubber has excellent resistance to oils and lubricants, it performs reliably in environments where sealing components are exposed to lubricating media.
