O-Ring 24x3 NBR 90 ShA

Overview

O-Ring 24x3 NBR 90 ShA is a sealing ring with a 24 mm inside diameter and 3 mm cross-section, manufactured from Nitrile Butadiene Rubber with a hardness of 90 Shore A. The higher hardness provides increased resistance to deformation and extrusion in demanding sealing arrangements. The product is supplied in packs of 100 pcs for industrial maintenance, service and B2B requirements.

Industrial Applications

The 24x3 NBR 90 ShA O-ring is suitable for appropriately designed hydraulic systems, fittings, valves, pumps, cylinders and industrial machinery. Its 90 ShA hardness is useful where greater resistance to deformation is required compared with standard 70 ShA compounds. NBR provides compatibility with many mineral oils, lubricants and suitable hydraulic fluids.

Construction

The O-ring has a circular 3 mm cross-section and nominal 24 mm inside diameter. When installed in a correctly designed groove, controlled compression between mating surfaces creates the sealing effect. Performance depends on groove geometry, compression, system pressure, extrusion gap, surface condition and correct installation.

Material

NBR, or Nitrile Butadiene Rubber, provides good resistance to many mineral oils, lubricating greases and compatible hydraulic fluids. The 90 Shore A hardness provides greater resistance to extrusion and deformation than softer NBR compounds. Actual temperature capability depends on the specific rubber compound, operating medium and application conditions.

FAQ

Why does the 24x3 O-ring use 90 ShA hardness?

The 90 Shore A compound provides greater resistance to deformation and extrusion than softer NBR grades.

How many O-rings are included in one package?

Each package contains 100 pcs of 24x3 NBR 90 ShA O-rings.

What is the outside diameter of a 24x3 O-ring?

The nominal outside diameter is approximately 30 mm.

Is NBR 90 ShA suitable for hydraulic applications?

Yes. NBR 90 ShA is commonly used in appropriately designed hydraulic sealing systems, particularly where increased extrusion resistance is required.

Can a 24x3 NBR 70 ShA O-ring replace the 90 ShA version?

Not automatically. Hardness affects deformation, sealing behavior and extrusion resistance, so the hardness specified for the sealing arrangement should be retained.
