O-ring NBR 22x3,5 mm 70 ShA

Applications & Industry Use

The O-Ring 22x3.5 NBR 70 ShA is a compact, durable nitrile rubber sealing ring designed for hydraulic, pneumatic and mechanical systems. With an inner diameter of 22 mm and a 3.5 mm cross-section, it is widely used in valves, pumps, actuators, small cylinders, fluid connectors, housings, gear mechanisms and maintenance operations requiring precise and reliable static sealing.
The bulk pack of 1000 pieces is ideal for OEM production, assembly lines, service departments and industrial maintenance teams looking for consistent quality and cost-efficient purchasing.

Technical Performance & Material Benefits

Made from NBR (nitrile butadiene rubber) with a hardness of 70 Shore A, this O-Ring provides the optimal balance of elasticity, mechanical strength and sealing performance. NBR is globally recognized for its excellent resistance to oils, hydraulic fluids, greases, fuels and many industrial chemicals, making these O-Rings suitable for equipment operating under exposure to lubricants and aggressive media.

Thanks to its low compression set and high wear resistance, the O-Ring maintains sealing performance even under pressure fluctuations, vibration and repeated duty cycles. The 3.5 mm profile ensures easy installation in narrow grooves, offering strong sealing capability while minimizing friction and deformation risks.

Advantages for B2B Buyers

• High chemical and oil resistance - ideal for hydraulic oils, mineral oils, greases and fuel-contact applications.

• Compact 3.5 mm cross-section - fits tight sealing grooves and precision assemblies.

• Consistent, repeatable dimensions - perfect for mass production and high-volume maintenance.

• Versatile industrial use - pumps, valves, cylinders, compressors, housings, connectors, and mechanical assemblies.

• Cost-effective bulk packaging - 1000-piece pack reduces downtime, packaging waste and procurement cycles.
