What Is the O-Ring 17x2 NBR 70 Shore A?
The O-Ring 17x2 NBR 70 Shore A is a precision industrial sealing ring manufactured from NBR (Nitrile Butadiene Rubber, Buna-N) with an inside diameter of 17 mm and a 2 mm cross section. With a hardness of 70 Shore A, it provides an excellent balance between elasticity and compression resistance, making it suitable for both static and many dynamic sealing applications. The O-ring is supplied in a 100-piece pack, making it an efficient solution for workshops, OEM production, maintenance departments and industrial service operations.
Why Choose NBR 70 Shore A?
NBR is the industry standard material for general-purpose sealing applications.
Key advantages include:
- Excellent resistance to mineral oils
- Good compatibility with lubricating greases
- Good resistance to hydraulic fluids
- High abrasion resistance
- Good mechanical strength
- Low compression set
- Reliable long-term sealing performance
The 70 Shore A hardness is the most commonly specified hardness for industrial O-rings because it combines flexibility with mechanical durability.
