O-ring 17x5 NBR 70 ShA

O-ring 17x5 NBR 70 ShA Nitrile Rubber Seal 100 pcs

O-ring 17x5 NBR 70 ShA is a technical sealing ring made from nitrile butadiene rubber designed for reliable sealing in hydraulic systems, pneumatic equipment and industrial machinery. The dimension 17x5 mm allows this sealing element to be installed in sealing grooves used in pumps, valves, hydraulic cylinders and many industrial mechanical assemblies. The product is supplied in packs of 100 pieces, making it a practical solution for maintenance departments, repair workshops and industrial production environments.

NBR nitrile O-rings are among the most widely used technical sealing components in industrial engineering. The NBR material offers very good resistance to mineral oils, greases and many petroleum based fluids commonly used in hydraulic and mechanical systems. A hardness level of 70 ShA provides the right balance between flexibility and durability, ensuring reliable sealing performance in demanding industrial conditions.

Industrial applications

The O-ring size 17x5 mm is used in many industrial systems that require durable sealing of mechanical components exposed to oils, lubricants and pressure.

Typical industrial applications include:

hydraulic systems
pneumatic installations
industrial pumps
technical valves
hydraulic cylinders
production machinery
general industrial equipment

NBR O-rings provide reliable sealing performance while maintaining a simple and efficient installation design.

Construction and design

The O-ring 17x5 NBR 70 ShA features a circular cross section that allows uniform compression between sealing surfaces. This geometry ensures effective sealing and prevents leakage of liquids and gases in mechanical systems.

Nitrile rubber combines elasticity with resistance to mechanical wear. The material maintains stable sealing performance in oil lubricated environments and in industrial installations operating under pressure and vibration.

A hardness level of 70 Shore A is widely used in sealing technology because it provides an optimal balance between elasticity and mechanical strength.
