O-ring 97x3 NBR

O-ring 97x3 NBR 70 ShA Nitrile Rubber Seal

O-ring 97x3 NBR 70 ShA is an industrial sealing ring manufactured from nitrile butadiene rubber designed for reliable sealing in hydraulic systems, pneumatic equipment and industrial machinery. The dimension 97x3 mm provides effective sealing in mechanical assemblies such as pumps, valves, hydraulic cylinders and various industrial machines. This type of technical seal is widely used in industry due to the good resistance of NBR material to oils, lubricants and many working fluids used in hydraulic and mechanical systems.

NBR nitrile O-rings are among the most commonly used sealing components in industrial engineering. The hardness of 70 ShA ensures an optimal balance between elasticity and durability, allowing the seal to operate reliably in installations exposed to pressure changes, vibration and mechanical loads.

Industrial applications

The O-ring size 97x3 mm is used in many industrial systems that require durable and reliable sealing of mechanical components.

Typical applications include:

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

NBR O-rings are widely applied where reliable sealing of oils, lubricants and industrial fluids is required.

Construction and design

The O-ring 97x3 NBR 70 ShA features a circular cross section that allows uniform compression between sealing surfaces. This geometry creates an effective sealing barrier that prevents leakage of liquids or gases.

NBR nitrile rubber combines flexibility with resistance to mechanical wear. The material maintains stable sealing performance in oil lubricated environments and under demanding industrial operating conditions.

A hardness level of 70 Shore A is widely used in industrial sealing applications because it provides the correct balance between flexibility and mechanical strength.
