NBR O-ring 47x3.5 mm 70 ShA Technical Seal

NBR Oring 47x3.5 mm 70 ShA Technical Seal

GRN NBR Oring 47x3.5 mm 70 ShA is a nitrile rubber sealing ring designed to provide reliable oil resistant sealing in hydraulic equipment, pneumatic systems and industrial machinery requiring durable elastomer seals.

Within the category of technical seals NBR Orings GRN, this dimensional configuration represents a medium cross section sealing ring frequently used in mechanical assemblies exposed to oils, lubricants and industrial fluids. GRN branded Orings are produced for industrial sealing applications where dimensional accuracy, oil resistance and stable compression properties are required.

The Oring NBR 47x3.5 mm is commonly searched using dimensional queries such as oring 47x3.5, NBR oring 47 mm, rubber sealing ring 47x3.5 mm, or nitrile O ring 3.5 mm cross section. These long tail queries typically appear during maintenance operations involving pumps, hydraulic valves, mechanical covers or industrial fluid systems where reliable sealing components are necessary.

With a hardness of 70 ShA, the nitrile rubber compound offers the correct balance between elasticity and mechanical strength. This allows the Oring to compress properly within the sealing groove while maintaining stable sealing performance under pressure and mechanical vibration.

In modern industrial equipment NBR Orings are widely used because they combine durability, chemical resistance and cost effective maintenance performance across a wide range of applications.

Construction and Material

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

Important material properties include:

excellent resistance to mineral oils
good compatibility with hydraulic fluids
high elasticity and compression recovery
good mechanical 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 GRN are widely used in hydraulic equipment, industrial machinery and mechanical maintenance applications.

Dimensional Compatibility

Proper dimensional selection is essential for reliable sealing performance.

The Oring 47x3.5 mm corresponds to the following dimensions:

Inner diameter: 47 mm
Cross section thickness: 3.5 mm
Outer diameter: 54 mm

This dimensional format is commonly used in sealing grooves found in pumps, valve housings, industrial machinery covers and hydraulic components.

Common dimensional search queries include:

NBR oring 47x3.5 mm
industrial nitrile O ring 47 mm ID
rubber sealing ring 3.5 mm cross section
oring seal 47 mm hydraulic application

Industrial Applications

Technical seals from the NBR Orings GRN category are widely used across industrial sectors where oil resistant elastomer sealing rings are required.

Typical applications include:

hydraulic systems in industrial machinery
