O-ring NBR 68x2.4 mm 70 Shore Technical Seal

Oring NBR 68x2.4 mm 70 Shore Technical Seal

Oring NBR 68x2.4 mm 70 Shore is a precision elastomer sealing ring designed to provide reliable oil resistant sealing in hydraulic systems, pneumatic installations and industrial machinery.

Within the category of Oringi NBR technical seals, this dimensional format is commonly used in medium size sealing assemblies where durable nitrile rubber sealing rings are required to prevent leakage of oils, lubricants and technical fluids. NBR elastomer is one of the most widely used sealing materials in industrial engineering due to its excellent resistance to mineral oils, greases and hydraulic fluids.

The Oring NBR 68x2.4 mm is often searched using dimensional queries such as oring 68x2.4, NBR oring 68 mm, rubber sealing ring 68x2.4 mm or industrial oring 68 mm inner diameter. These dimensional search phrases are typical for maintenance engineers and technicians looking for precise replacement seals for pumps, valves and hydraulic assemblies.

The elastomer hardness of 70 Shore A provides an optimal balance between flexibility and mechanical strength. This allows the Oring to compress correctly inside sealing grooves and maintain stable sealing performance under pressure and vibration.

In the broader cluster of Oringi NBR technical seals, the 68x2.4 mm size is widely applied in industrial equipment where reliable sealing and dimensional precision are essential for system safety and operational efficiency.

Industrial Applications

Technical sealing rings from the Oringi NBR category are widely used in many industrial sectors where oil resistant elastomer seals are required.

Typical applications include:

hydraulic systems
pneumatic control systems
industrial pumps and compressors
gearbox lubrication circuits
mechanical assemblies in production machinery
automotive fluid systems

In many of these installations the Oring 68x2.4 mm functions as a static or low speed dynamic seal preventing leakage of fluids and maintaining pressure stability.

Construction and Material

The sealing ring is manufactured from NBR nitrile rubber, an elastomer specifically engineered for industrial sealing environments exposed to oils and lubricants.

NBR materials offer:

excellent resistance to mineral oils
good resistance to fuels and lubricants
high elasticity for compression sealing
good mechanical durability and wear resistance

The circular cross section of the Oring allows uniform deformation inside the sealing groove. When compressed between sealing surfaces it forms an effective barrier preventing leakage of liquids or gases.

Because of these properties NBR Orings are one of the most common sealing solutions used in industrial machinery and maintenance operations.
