O-Ring 165x10 NBR

Material Characteristics and Performance

The O-Ring 165x10 NBR 70 ShA is a precision-molded sealing element manufactured from nitrile butadiene rubber (NBR) with a standard hardness of 70 Shore A. NBR is widely recognized for its strong resistance to mineral oils, hydraulic fluids, fuel blends, lubricants, and water-based solutions, making it one of the most commonly specified elastomers in industrial sealing applications.
This O-ring provides a stable, durable seal in static interfaces and can also be used in low-movement dynamic systems when installed in properly engineered grooves. With a working temperature range of approximately -30°C to +100°C, it maintains elasticity and sealing integrity under typical operational conditions found in mechanical assemblies, hydraulic equipment, compressor housings, and valve components.

Applications in Hydraulic, Pneumatic, and Mechanical Systems

The O-Ring 165x10 NBR 70 ShA is suitable for use in hydraulic cylinders, pneumatic control systems, flanged housings, pumps, gearboxes, pipe connections, and pressure-bearing enclosures. It is commonly utilized across sectors such as machinery manufacturing, automotive and agricultural equipment service, industrial maintenance, and process engineering.
Its 10 mm cross-section provides robust sealing contact pressure, making it ideal for larger diameter sealing surfaces where secure static sealing is essential.

FAQ

Is NBR 70 ShA suitable for use with hydraulic oil?
Yes. NBR is one of the primary elastomers used in hydraulic sealing due to its excellent resistance to oil-based media.

Can this O-ring operate at high temperatures?
Typical operating limits are approximately -30°C to +100°C, depending on system conditions and pressure.

Is this O-ring intended for dynamic sealing?
It may be used in slow or limited movement dynamic environments, but it is primarily recommended as a static seal to achieve maximum longevity.

Why is 70 Shore A hardness standard?
70 ShA provides a balanced combination of sealing pressure, flexibility, and abrasion resistance suitable for general-purpose industrial use.
