NBR O-Ring 15x2 mm 70 ShA

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

NBR is widely used for industrial O-rings due to its good resistance to mineral oils, lubricating greases and many mineral oil-based hydraulic fluids.

Packaging: 100 pieces.

NBR 70 ShA Material

NBR (Nitrile Butadiene Rubber) is one of the most commonly used elastomers for industrial sealing elements. It provides good resistance to mineral oils, greases and many petroleum-based fluids.

70 Shore A is a widely used hardness grade for general-purpose industrial O-rings, providing a practical balance between elasticity, sealing capability and mechanical stability.

Chemical Resistance

NBR generally provides good resistance to:

• mineral oils,
• lubricating greases,
• mineral oil-based hydraulic fluids,
• many hydrocarbons,
• water under suitable operating conditions.

Chemical compatibility should always be verified for the specific fluid, concentration and operating temperature.

Temperature Range

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

-30°C to +100°C

Actual temperature limits depend on the specific NBR compound, operating medium and duration of exposure.

Typical Applications

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

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

Operational Advantages

• Standard 15x2 mm dimensions
• NBR 70 Shore A material
• Good mineral oil resistance
• Good grease resistance
• Suitable for hydraulic and pneumatic systems
• Industrial pack of 100 pieces
