O-ring 470x4 NBR 70 ShA Nitrile Rubber Sealing Ring

Industrial applications

O-ring 470x4 NBR 70 ShA is a large diameter nitrile rubber sealing ring designed for reliable sealing in industrial equipment, hydraulic installations and mechanical assemblies. This sealing component belongs to the category of technical sealing O-rings NBR widely used in machinery, processing systems and industrial maintenance operations.

The dimension 470x4 mm is typically used in large housings, tanks, covers and industrial components where effective sealing between two surfaces is required. The nitrile rubber compound provides good resistance to mineral oils, lubricants, fuels and many technical fluids commonly used in industrial systems.

O-ring 470x4 NBR 70 ShA is commonly installed in pump housings, industrial valves, filtration systems, hydraulic units and mechanical equipment where large diameter sealing elements are required. Maintenance engineers and industrial service teams frequently use large NBR O-rings for sealing inspection covers, service lids and structural connections.

Because of its large diameter, this sealing ring is often applied in heavy machinery, processing installations and industrial systems where reliable sealing of larger components is necessary.

Construction and material

The sealing ring is manufactured from NBR nitrile rubber with hardness 70 ShA, one of the most widely used materials in the category of industrial O-rings. Nitrile rubber offers a balanced combination of elasticity, durability and chemical resistance.

The circular cross section allows the O-ring to compress evenly inside a sealing groove. When installed, the elastomer deforms slightly and creates a tight sealing barrier between the mating surfaces, preventing leakage of fluids or gases.

NBR material provides reliable resistance to mineral oils, greases and fuels, which makes this O-ring suitable for use in hydraulic systems, lubrication circuits and industrial machinery.

The design of O-ring 470x4 NBR 70 ShA allows it to maintain sealing performance in both static and lightly dynamic applications.

Dimensional compatibility

The designation O-ring 470x4 refers to an inner diameter of 470 mm and a cross section thickness of 4 mm. This dimensional format is used in large industrial sealing grooves and mechanical assemblies requiring elastomer sealing elements.

Proper groove design and correct compression ratio are essential to achieve effective sealing performance. When correctly installed, the nitrile rubber O-ring expands slightly within the groove and forms a secure seal against leakage.

Operational advantages

NBR O-rings are widely used in industrial sealing applications due to their durability and cost efficiency. The O-ring 470x4 NBR 70 ShA provides reliable sealing performance in large diameter assemblies and industrial installations.

The 70 ShA hardness ensures the correct balance between flexibility and structural stability, allowing the sealing ring to maintain compression while adapting to surface irregularities.

In addition, nitrile rubber offers good resistance to oils and lubricants, which helps extend the operational life of the sealing component in industrial working conditions.

Large diameter O-rings such as 470x4 are commonly used in industrial equipment where maintenance teams require durable and easily replaceable sealing elements.
