NBR O-Ring 8x1 mm 70 ShA

What is the O-Ring 8x1 mm NBR 70 ShA 1000 pcs?

NBR O-Ring 8x1 mm 70 ShA is a technical elastomer sealing ring with an 8 mm inside diameter and 1 mm cross-section, manufactured from NBR (Nitrile Butadiene Rubber) with a hardness of 70 Shore A.

NBR is widely used for industrial sealing due to its good resistance to mineral oils, lubricating greases and many mineral oil-based hydraulic fluids. This product is supplied in a bulk pack of 1000 pieces, suitable for industrial production, maintenance and service applications.

NBR 70 Shore A Material

NBR (Nitrile Butadiene Rubber) is one of the most commonly used elastomers for industrial O-rings and technical sealing components.

Its main properties include:

• good resistance to mineral oils,
• good resistance to lubricating greases,
• compatibility with many mineral oil-based hydraulic fluids,
• good mechanical properties,
• wide use in industrial sealing systems.

A hardness of 70 Shore A is a standard specification for many general-purpose industrial O-rings.

Chemical Resistance

NBR generally provides good resistance to mineral oils, lubricating greases, many hydrocarbons and mineral oil-based hydraulic fluids.

Chemical compatibility depends on the specific NBR compound, operating medium, concentration, temperature and exposure time.

Operating Temperature

For standard NBR 70 Shore A compounds, a typical operating temperature range is approximately:

-30°C to +100°C

The actual permissible temperature range depends on the specific compound and operating medium.

Typical Applications

The NBR O-Ring 8x1 mm 70 ShA can be used in appropriately designed:

• hydraulic systems,
• pneumatic systems,
• pumps and valves,
• technical fittings,
• industrial machinery,
• mechanical equipment,
• oil systems,
• static sealing connections,
• suitable dynamic sealing arrangements.
