O-Ring 595x20 NBR 70 ShA

O-Ring 595x20 NBR 70 ShA - Heavy Duty Technical Sealing

The O-Ring 595x20 NBR 70 ShA is a large diameter industrial rubber seal designed for demanding sealing applications where reliability and durability are critical. The 595x20 dimension refers to an inner diameter of 595 mm and a 20 mm cross section, making this O-Ring suitable for heavy duty housings, large covers, tanks and industrial assemblies.

Manufactured from Nitrile Butadiene Rubber NBR with a hardness of 70 ShA, this sealing ring provides high resistance to oils, greases and fuels commonly used in industrial systems. The balanced mechanical properties of NBR 70 ShA combine flexibility with structural strength, ensuring long service life and consistent sealing performance even in large scale installations.

Applications in Hydraulic and Industrial Systems

The O-Ring 595x20 NBR 70 ShA is primarily used as a static seal in large industrial constructions. Typical applications include:

• sealing rings for large flanges and covers

• rubber gaskets in tanks and industrial housings

• sealing components in hydraulic systems

• maintenance parts for heavy machinery

Thanks to its high oil resistance and dimensional stability, this O-Ring supports leak prevention and pressure retention in industrial and hydraulic applications.

Material Properties and Performance

NBR 70 ShA is one of the most widely specified elastomers for industrial sealing. The O-Ring 595x20 offers:

• high resistance to mineral oils, greases and fuels

• good abrasion resistance

• stability under compression

• reliable static sealing in industrial environments

The 70 ShA hardness ensures an optimal balance between elasticity and mechanical durability, which is particularly important for large cross section sealing rings.
