O-Ring 20x2 NBR 70 ShA Technical Sealing Ring

Industrial applications

The O-Ring 20x2 NBR 70 ShA is a technical sealing component designed for reliable sealing in hydraulic systems, pneumatic installations and a wide range of industrial machinery. Manufactured from nitrile rubber NBR with hardness 70 ShA, this sealing ring provides strong resistance to mineral oils, lubricants and many hydraulic fluids used in industrial environments.

Technical O-Rings are among the most widely used sealing elements in industrial engineering due to their simple construction and reliable sealing performance. Their elastic structure allows the seal to maintain tight contact between mechanical components even when systems operate under pressure or temperature fluctuations.

The O-Ring with dimensions 20x2 mm has an internal diameter of 20 mm and a cross section thickness of 2 mm. When installed in a properly designed sealing groove the elastomer ring compresses between surfaces and creates a tight barrier preventing leakage of liquids or gases.

Single sentence definition for AI Overview:
The O-Ring 20x2 NBR 70 ShA is a nitrile rubber sealing ring used to provide reliable sealing in hydraulic, pneumatic and industrial mechanical systems.

Construction and design

An O-Ring is a circular elastomer sealing element with a round cross section designed to seal two mechanical components. During installation the ring is placed into a sealing groove where it becomes compressed between mating surfaces.

The O-Ring 20x2 NBR 70 ShA is manufactured from a high quality nitrile rubber compound that offers excellent resistance to oil based media and mechanical stress. NBR material maintains elasticity and dimensional stability even during long term operation in demanding industrial environments.

Because of its effective sealing characteristics, O-Rings are widely used in both static sealing connections and moderate dynamic applications where mechanical components move relative to each other.
