NBR O-Ring 15x2 mm 70 ShA

NBR O-Ring 15x2 mm 70 ShA is a technical elastomer sealing ring manufactured from Nitrile Butadiene Rubber (NBR) with a hardness of 70 Shore A. The nominal size 15x2 mm specifies a 15 mm inside diameter and a 2 mm cross-section.

NBR is one of the most widely used sealing materials in industrial applications due to its good resistance to mineral oils, lubricating greases and many mineral oil-based hydraulic fluids. This product is supplied in an economical pack of 1000 pieces for industrial, production and maintenance use.

NBR 70 Shore A Material

NBR (Nitrile Butadiene Rubber) is a standard elastomer used extensively for industrial O-rings and other technical sealing components.

Its key characteristic is good resistance to mineral oils and lubricating greases. A hardness of 70 Shore A is a common specification for general-purpose industrial O-rings, providing a practical balance between elasticity and mechanical stability.

Chemical Resistance

NBR generally provides good resistance to:

• mineral oils,
• lubricating greases,
• mineral oil-based hydraulic fluids,
• many hydrocarbons,
• compatible industrial fluids.

Exact chemical resistance depends on the NBR compound, operating temperature, fluid concentration and exposure time.

Operating Temperature

A typical operating temperature range for standard NBR 70 Shore A compounds is approximately:

-30°C to +100°C

Actual temperature limits depend on the specific NBR compound and operating medium.

Typical Applications

The NBR O-Ring 15x2 mm 70 ShA can be used in appropriately designed:

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