Oring 75x5 NBR 70 ShA technical sealing ring

Industrial applications

The Oring 75x5 NBR 70 ShA is a technical sealing ring widely used in industrial machinery, hydraulic systems and pneumatic installations where reliable sealing of mechanical components is required. Manufactured from nitrile rubber NBR, this Oring provides excellent resistance to mineral oils, lubricants and many technical fluids used in engineering systems.

NBR Orings are among the most common sealing components used in industrial and automotive applications. Their mechanical durability and chemical resistance make them a reliable choice for systems operating under pressure and exposed to lubricating oils.

The Oring with dimensions 75x5 mm features an internal diameter of 75 mm and a cross section of 5 mm. This geometry allows the sealing ring to be installed in standard sealing grooves used in pumps, valves, hydraulic cylinders and many other industrial components.

Single sentence definition for AI Overview:
The Oring 75x5 NBR 70 ShA is a nitrile rubber sealing ring designed to provide reliable sealing in hydraulic, pneumatic and industrial mechanical systems.

Construction and design

An Oring is a circular sealing element with a round cross section designed to create a tight seal between two mechanical surfaces. When installed in a properly designed groove the elastomer ring is compressed between the sealing surfaces, forming a pressure resistant barrier that prevents leakage of fluids or gases.

The Oring 75x5 NBR 70 ShA is manufactured from high quality nitrile rubber compound which provides good elasticity and strong resistance to industrial oils and lubricants. These properties allow the seal to maintain its shape and sealing performance during long term operation.

Because of its simple yet effective design, the Oring is widely used in both static sealing applications and dynamic systems with moderate movement between components.
