O-ring NBR 17.17x1.78 mm 70 Shore Technical Seal

Oring NBR 17.17x1.78 mm 70 Shore Technical Seal

Oring NBR 17.17x1.78 mm 70 Shore is a precision nitrile rubber sealing ring designed for reliable sealing in hydraulic systems, pneumatic installations and industrial machinery operating with oils and technical fluids.

Within the category of technical seals NBR Orings, this dimensional configuration belongs to compact sealing components commonly used in valves, pumps and fluid control assemblies where precise elastomer sealing is required. NBR nitrile rubber is widely used in industrial sealing technology because it offers excellent resistance to mineral oils, greases and many industrial fluids.

The Oring NBR 17.17x1.78 mm is often searched using dimensional queries such as oring 17.17x1.78, NBR oring 17 mm, rubber sealing ring 17.17x1.78 mm, or nitrile O ring 1.78 mm cross section. These dimensional long tail queries typically appear during maintenance of hydraulic valves, pneumatic fittings, pumps and mechanical components requiring precise replacement seals.

With a hardness of 70 Shore A, the nitrile rubber compound provides an optimal balance between elasticity and mechanical strength. This allows the Oring to compress correctly within sealing grooves while maintaining stable sealing performance under pressure, vibration and exposure to oils or lubricants.

In industrial machinery NBR Orings are widely used because they combine durability, chemical resistance and reliable sealing performance across a wide range of technical applications.

NBR oring 17.17x1.78 mm
rubber sealing ring 17 mm ID
industrial nitrile O ring 1.78 mm cross section
oring seal 17 mm hydraulic application

Construction and Material

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

Key material properties include:

excellent resistance to mineral oils
good compatibility with hydraulic fluids
high elasticity and compression recovery
good durability in industrial environments

The circular cross section of the Oring allows uniform compression inside the sealing groove. When installed between sealing surfaces the elastomer forms a tight sealing barrier preventing leakage of liquids or gases.

Because of these characteristics technical seals NBR Orings are widely used in hydraulic systems, industrial automation equipment and mechanical maintenance operations.

Industrial Applications

Technical seals from the NBR Orings category are used across many industries where oil resistant elastomer seals are required.

Typical applications include:

hydraulic control systems
pneumatic automation equipment
industrial pumps and compressors
fluid distribution blocks
machine lubrication systems
automotive fluid components

In these installations the Oring 17.17x1.78 mm often functions as a static seal preventing leakage of oil or compressed air within mechanical assemblies.

Operational Advantages

Maintenance engineers frequently select NBR Orings because they combine reliable sealing performance with durability and cost efficiency.

Key advantages include:

excellent resistance to oils and lubricants
stable sealing performance under compression
high elasticity and recovery
good wear resistance in mechanical systems
economical sealing solution for industrial maintenance

These properties make nitrile rubber sealing rings a standard component in industrial sealing technology.
