O-ring NBR 4x2 mm 70 ShA

Application in industrial sealing systems

The O-ring NBR 4x2 70 ShA is a precision sealing element designed for industrial applications where consistent quality and reliable sealing are required in high volume usage.

An O-ring is a circular elastomer seal that provides tight sealing by compression in a groove, ensuring leak prevention in both static and dynamic systems.

This 4x2 mm O-ring in a 1000 pcs package is commonly used in:

• automated production lines
• pneumatic and hydraulic assemblies
• industrial valves and connectors
• compact mechanical devices

Its small size makes it ideal for precision applications where space is limited but sealing performance must remain stable.
