O-Ring 95x2 NBR 70 ShA - Industrial Rubber Seal

Industrial Application and Working Environment

The O-Ring 95x2 NBR 70 ShA is a precision engineered rubber sealing ring designed for industrial, hydraulic and pneumatic systems. The 95x2 dimension indicates an inner diameter of 95 mm and a 2 mm cross section, ensuring accurate fit in standard groove designs used in machine housings, covers and mechanical assemblies.

This O-Ring is primarily used as a static seal in applications where reliable pressure retention and leak prevention are critical. It is widely selected by maintenance departments, machine manufacturers and industrial buyers looking for durable technical sealing components.

Material Properties and Technical Performance

Manufactured from Nitrile Butadiene Rubber NBR with a hardness of 70 ShA, this O-Ring offers high resistance to mineral oils, greases and fuels. NBR 70 ShA is one of the most commonly specified elastomers for industrial sealing due to its balanced combination of elasticity and mechanical strength.

The material provides good abrasion resistance and dimensional stability under compression. As a rubber gasket and sealing ring, it maintains consistent sealing performance under varying temperatures and mechanical loads.

Why This Type of Sealing Is Optimal

Hydraulic and pneumatic sealing systems require materials with strong resistance to oils and reliable compression behavior. The O-Ring 95x2 NBR 70 ShA meets these requirements by providing durable static sealing without excessive deformation.

The 2 mm cross section allows proper compression within the groove, ensuring even load distribution and minimizing the risk of leakage. This makes it a dependable solution for industrial applications where long service life and predictable performance are essential.
