NBR O-ring 48x3 mm 70 Shore

NBR Oring 48x3 mm 70 Shore Technical Seal

GRN NBR Oring 48x3 mm 70 Shore is an industrial nitrile rubber sealing ring designed to ensure reliable sealing in hydraulic systems, pneumatic installations and machinery operating with oils and technical fluids.

Within the category of technical seals NBR Orings GRN, this dimensional format belongs to medium cross section sealing elements used in industrial equipment requiring durable elastomer sealing rings. GRN branded Orings are manufactured for industrial sealing applications where stable compression, oil resistance and long service life are required.

The Oring NBR 48x3 mm is commonly searched using dimensional phrases such as oring 48x3, NBR oring 48 mm, rubber sealing ring 48x3 mm, or nitrile O ring 3 mm cross section. These long tail dimensional queries often appear during maintenance of pumps, hydraulic valves, machine covers and industrial fluid systems where accurate seal replacement is required.

With a hardness of 70 ShA, the nitrile rubber compound provides the correct balance between elasticity and mechanical strength. This allows the Oring to compress properly inside the sealing groove and maintain stable sealing performance under pressure, vibration and contact with oils or lubricants.

In modern mechanical systems NBR Orings are widely used because they provide reliable sealing performance, chemical resistance and cost effective maintenance solutions for industrial equipment.

Construction and Material

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

Important material characteristics 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 ensures uniform deformation inside the sealing groove. When compressed between sealing surfaces the elastomer forms a tight barrier preventing leakage of liquids or gases.

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

Dimensional Compatibility

Correct dimensional selection is critical for reliable sealing performance.

The Oring 48x3 mm corresponds to the following parameters:

Inner diameter: 48 mm
Cross section thickness: 3 mm
Outer diameter: 54 mm

This dimensional configuration is commonly used in sealing grooves found in pumps, valves, machine housings and industrial fluid installations.

Typical dimensional search queries include:

NBR oring 48x3 mm
industrial nitrile O ring 48 mm ID
rubber sealing ring 3 mm cross section
oring seal 48 mm hydraulic application

Industrial Applications

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

Typical applications include:
