O-Ring 23x2.5 NBR 70 ShA

O-Ring 23x2.5 NBR for General Technical Sealing

O-Ring 23x2.5 NBR 70 ShA - 100 pcs is a flexible sealing ring designed for reliable sealing in machinery, fittings and a wide range of technical equipment.

The 23x2.5 mm dimensions indicate a 23 mm inside diameter and 2.5 mm cross-section. The widely used NBR 70 Shore A compound provides a practical balance between elasticity, mechanical properties and resistance to many common industrial lubricants.

This variant is supplied in a pack of 100 pcs, making it particularly suitable for maintenance departments, workshops, technical service companies and small to medium production requirements.

NBR 70 Shore A - Standard Industrial Hardness

70 ShA is one of the most commonly used hardness levels for technical NBR O-rings.

Compared with harder compounds such as NBR 90 ShA, the 70 ShA material is more flexible and can conform effectively to the sealing groove when correctly compressed.

Hardness is an important part of the O-ring specification. A 23x2.5 NBR 90 ShA O-ring should therefore not automatically be used as a replacement for this 70 ShA version solely because the dimensions are identical.

NBR Material Properties

NBR - Nitrile Butadiene Rubber is widely used for industrial sealing applications involving many:

• mineral oils
• lubricating greases
• hydraulic oils
• industrial lubricants
• compatible technical fluids

Actual suitability depends on the specific medium, operating temperature, pressure and sealing conditions.

O-Ring 23x2.5 Dimensions

Inside Diameter (ID): 23 mm
Cross-Section (CS): 2.5 mm
Calculated Outside Diameter (OD): 28 mm
Hardness: 70 Shore A
Pack Quantity: 100 pcs

Correct O-ring selection should consider not only dimensions but also material, hardness and operating conditions.

Typical Applications

The 23x2.5 NBR 70 ShA O-Ring can be used in appropriately designed:

• industrial machinery
• pumps and valves
• hydraulic systems
• pneumatic systems
• mechanical assemblies
• lubrication systems
• technical equipment
• maintenance and repair applications

It is primarily suitable for static sealing and can also be used in appropriately engineered dynamic sealing arrangements.

Technical Specification

100 pcs Pack for Maintenance and Service

The 100 pcs pack provides a practical quantity for users who need a regular stock of 23x2.5 mm O-rings without purchasing a larger industrial bulk package.

This variant is particularly suitable for maintenance departments, repair workshops, technical services and small to medium production batches.

For applications with substantially higher consumption, a separate bulk-pack variant may be more appropriate.

Operational Advantages

• 23x2.5 mm nominal dimensions
• standard 70 Shore A hardness
• flexible NBR sealing material
• good resistance to many mineral oils and greases
• suitable for numerous technical sealing applications
• useful for maintenance, repair and machine assembly
• practical 100 pcs packaging

FAQ

What are the dimensions of the O-Ring 23x2.5 NBR 70 ShA?
The nominal dimensions are 23 mm inside diameter and 2.5 mm cross-section. The calculated outside diameter is 28 mm.

What does 70 ShA mean?
70 ShA indicates a nominal hardness of 70 Shore A, a widely used hardness for standard technical NBR O-rings.

What is the difference between 23x2.5 NBR 70 ShA and 90 ShA?
Both versions have the same nominal dimensions, but their mechanical properties differ. 70 ShA is more flexible, while 90 ShA is harder and offers greater resistance to deformation and extrusion.

Is NBR 70 ShA suitable for oil applications?
NBR provides good resistance to many mineral oils, hydraulic oils and lubricating greases. Compatibility should always be verified for the specific operating medium.

Where can a 23x2.5 NBR O-ring be used?
Typical applications include machinery, pumps, valves, hydraulic and pneumatic systems, mechanical assemblies and general industrial maintenance.

How many O-rings are included?
This product variant contains 100 pcs of 23x2.5 NBR 70 ShA O-rings.
