O-Ring 35x4 NBR 70 ShA Technical Sealing Ring

Construction and design

The O-Ring 35x4 NBR 70 ShA is a precision technical sealing ring designed for use in hydraulic systems, pneumatic installations and a wide range of industrial machinery. Manufactured from nitrile rubber NBR with hardness 70 ShA, this sealing component provides reliable resistance to mineral oils, lubricants and many hydraulic fluids used in industrial equipment.

Technical O-Rings are among the most commonly used sealing solutions in mechanical engineering due to their simple geometry and high reliability. Their elastomer structure allows the seal to maintain tight contact with mating surfaces even under pressure and temperature fluctuations.

The O-Ring with dimensions 35x4 mm has an internal diameter of 35 mm and a cross section thickness of 4 mm. When installed in a correctly designed sealing groove, the elastomer ring compresses between surfaces and forms a durable barrier preventing leakage of liquids or gases.
