Oring 49.5x3 NBR 70 ShA technical sealing ring

Construction and design

The Oring 49.5x3 NBR 70 ShA is a precision technical sealing ring designed for use in hydraulic systems, pneumatic installations and various industrial machines. Manufactured from nitrile rubber NBR with hardness 70 ShA, it offers excellent resistance to mineral oils, lubricants and many industrial fluids.

NBR Orings are among the most widely used sealing elements in mechanical engineering due to their balanced combination of elasticity, chemical resistance and durability. The material maintains stable sealing properties under pressure and during long term operation.

The Oring with dimensions 49.5x3 mm features an internal diameter of 49.5 mm and a cross section of 3 mm. When installed in a properly designed groove, the elastomer ring compresses between two surfaces, forming a tight sealing barrier that prevents leakage of liquids or gases.
