O-ring 16x3 NBR 70 ShA

Industrial applications

O-ring 16x3 NBR 70 ShA is a nitrile rubber sealing ring designed for reliable sealing in hydraulic systems, pneumatic equipment and industrial machinery. This component belongs to the category of technical sealing O-rings NBR widely used in mechanical engineering, maintenance operations and industrial production environments.

The 16x3 mm sealing dimension is commonly applied in valves, pumps, compressors and machine assemblies where consistent sealing performance is required. Thanks to the nitrile rubber compound, the O-ring provides resistance to mineral oils, fuels, lubricants and water commonly present in technical systems.

O-ring 16x3 NBR 70 ShA is frequently used in hydraulic connectors, pneumatic control units, automotive service equipment and industrial machines. Maintenance engineers and production technicians often use this size when replacing worn sealing components in mechanical systems.

The pack of 100 pieces makes this product particularly suitable for industrial maintenance departments, repair workshops, technical distributors and manufacturing plants that require a steady supply of standard sealing components.

Construction and material

This nitrile rubber sealing ring is manufactured from high quality NBR elastomer with hardness 70 ShA. NBR is one of the most widely used materials in the category of industrial O-rings due to its balanced mechanical properties and chemical resistance.

The circular cross section design ensures uniform compression inside sealing grooves, allowing the O-ring to maintain stable contact pressure and reliable sealing performance. This geometry allows the sealing ring to operate effectively in static and lightly dynamic applications.

Nitrile rubber offers strong resistance to oils, lubricants and fuels, which makes it a suitable material for hydraulic systems, automotive equipment and industrial machinery where contact with technical fluids occurs.

Dimensional compatibility

The designation O-ring 16x3 refers to an inner diameter of 16 mm and a cross section thickness of 3 mm. These dimensions correspond to common sealing groove designs used in industrial hydraulic and pneumatic components.

Proper dimensional compatibility ensures correct compression and sealing efficiency. When installed in the appropriate groove, the nitrile rubber sealing ring expands slightly and forms a tight barrier preventing leakage of fluids or gases.

Because the 16x3 dimension is widely used in industrial maintenance, this NBR O-ring is often selected as a replacement sealing component in pumps, valves, hydraulic fittings and mechanical service kits.

Typical long tail search phrases include O-ring 16x3 NBR, industrial O-ring 16x3 mm, nitrile rubber sealing ring 16x3, NBR O-ring 16x3 70 ShA and O-ring 16x3 pack of 100.

Operational advantages

O-rings NBR 70 ShA nitrile rubber sealing rings are widely recognized for their reliability and versatility. The O-ring 16x3 model provides an efficient sealing solution across many industrial applications where oil resistant elastomer seals are required.

The 70 ShA hardness offers a balanced combination of flexibility and structural strength. This allows the sealing ring to compress properly in the sealing groove while maintaining long term sealing performance.

Bulk packaging of 100 pieces improves operational efficiency for B2B customers. Industrial buyers can maintain stock availability and quickly replace worn sealing components during maintenance procedures.
