O-Ring 12x1.2 NBR 70 ShA

Product Overview

O-Ring 12x1.2 NBR 70 ShA is a technical sealing ring manufactured from Nitrile Butadiene Rubber (NBR) with a hardness of 70 Shore A. The dimensions 12x1.2 mm indicate a 12 mm inside diameter and a 1.2 mm cross-section.

NBR is one of the most widely used elastomers for industrial O-rings because of its good resistance to mineral oils, lubricating greases and many compatible technical fluids. The small 1.2 mm cross-section makes this O-ring suitable for compact sealing grooves and precision mechanical assemblies.

The product is supplied in packs of 100 pieces, suitable for industrial maintenance, MRO inventory, workshops and production requirements.

Industrial Applications

O-Rings manufactured from NBR 70 ShA are commonly used in:

• hydraulic systems
• pneumatic systems
• pumps and valves
• industrial machinery
• oil systems
• technical fittings
• mechanical equipment
• precision sealing assemblies
• maintenance and repair operations

Selection should consider groove dimensions, operating pressure, temperature, sealing medium and whether the application is static or dynamic.

NBR 70 ShA Material

NBR (Nitrile Butadiene Rubber) provides a useful combination of oil resistance and mechanical properties, making it a standard material for numerous industrial sealing applications.

Key characteristics include:

• good resistance to many mineral oils
• good resistance to lubricating greases
• good abrasion resistance
• useful mechanical strength
• standard 70 ShA hardness
• wide industrial applicability

NBR is not compatible with every chemical or operating environment. Material compatibility should always be verified for the specific medium and service conditions.

FAQ

What are the dimensions of the O-Ring 12x1.2 NBR 70 ShA?
The O-ring has a 12 mm inside diameter and a 1.2 mm cross-section.

What does 70 ShA mean?
70 ShA indicates the elastomer hardness measured on the Shore A scale. It is a commonly used hardness for general-purpose NBR O-rings.

Is the 12x1.2 NBR O-ring oil resistant?
NBR provides good resistance to many mineral oils and lubricating greases. Compatibility should always be verified for the specific fluid and operating temperature.

Can this O-ring be used in hydraulic and pneumatic systems?
Yes. NBR O-rings are widely used in hydraulic and pneumatic systems when their dimensions, material properties and operating conditions match the application requirements.

Why is the 1.2 mm cross-section important?
The 1.2 mm cross-section allows the O-ring to fit compact sealing grooves where a small sealing profile is required.

How many O-rings are included in the package?
Each package contains 100 O-Rings 12x1.2 NBR 70 ShA.
