O-Ring 10x1.8 NBR

Product Overview

The O-Ring 10x1.8 NBR 70 ShA is a precision-engineered nitrile rubber sealing ring designed for reliable performance in industrial systems. The 70 ShA hardness rating ensures a balanced combination of flexibility and mechanical strength, making this O-ring suitable for static sealing interfaces and low-dynamic applications commonly found in hydraulic and pneumatic equipment.

Material Characteristics and Advantages

NBR (Nitrile Butadiene Rubber) is one of the most widely used materials for sealing components due to its excellent resistance to mineral oils, lubricants, fuels, hydraulic fluids, and standard industrial operating conditions. The material maintains stable elasticity, ensuring consistent sealing pressure and preventing leakage during prolonged operation.

Key Benefits:
• Excellent resistance to oils, greases, and hydraulic fluids
• Reliable sealing performance in industrial environments
• Durable structure and low compression set
• Suitable for standard hydraulic and pneumatic applications
• Supplied in convenient bulk packaging for maintenance operations

Industrial Applications

This O-ring is widely applied in:
• Hydraulic pumps and cylinders
• Pneumatic valves and actuators
• Industrial machinery and service equipment
• Lubrication systems and fuel handling components
• Static sealing interfaces, threaded connections and housings

Main Description

The O-Ring 10x1.8 NBR 70 ShA is an industrial-grade sealing component designed to ensure secure and leak-free performance in equipment exposed to oils, lubricants, hydraulic media, and compressed air. The mechanical properties of nitrile rubber provide the flexibility required to create a uniform sealing surface, while maintaining shape stability and sealing pressure under operational load.

This O-ring is optimized for static sealing applications, such as sealed housings, threaded connectors, flange interfaces, and component enclosures. It can also be used in low-dynamic environments where occasional vibration or small mechanical movement occurs, without compromising sealing capability. Its 70 ShA hardness is considered the industry standard for general-purpose sealing, ensuring compatibility with the majority of hydraulic and pneumatic groove geometries.

The bulk pack of 100 units is ideal for maintenance departments, OEM assembly lines, industrial repair workshops, and spare parts distribution. This format supports efficient replacement cycles, reduces downtime, and ensures sealing availability during routine equipment servicing.

With consistent dimensional accuracy and stable material performance, the O-Ring 10x1.8 NBR 70 ShA serves as a dependable sealing solution for demanding technical applications.

FAQ

What is the temperature range for NBR O-rings?
Approximately -30°C to +100°C, depending on fluid and system conditions.

Is NBR resistant to oils and hydraulic fluids?
Yes. NBR offers excellent resistance to mineral oils, lubricants, and hydraulic fluids.

Is this O-ring suitable for potable water or food applications?
No. For sanitary or food-contact applications, EPDM or silicone (MVQ) is recommended.
