 NBR70 O-Ring | O Ring Seal | Industrial Oil-Resistant Seal

Product Description


This A120 NBR70 O-Ring, sized 25x2.62mm, is a reliable industrial sealing component made of premium nitrile butadiene rubber. Formulated to 70 Shore A hardness, it balances elasticity and structural stability, delivering consistent sealing performance between -40°C and 120°C. The black, one-piece circular design fits standard seal grooves in industrial pumps, hydraulic valves, and automotive gearboxes, creating a durable barrier against oil, gas, and fluid leakage. Its NBR70 material offers excellent resistance to mineral oils, hydraulic fluids, and wear, making it suitable for both static and dynamic sealing applications in harsh industrial environments.

Advantages

  • Excellent Oil Resistance: NBR70 material exhibits strong tolerance to mineral oils, hydraulic fluids, and petroleum-based media, ideal for oil-contact applications.
  • Optimized Hardness & Elasticity: The 70 Shore A hardness formula provides a balance of sealing pressure and resilience, maintaining a tight seal even under dynamic conditions.
  • Wide Temperature Range: Operates reliably from -40°C to 120°C, adapting to fluctuating temperatures in industrial and automotive settings.
  • Durable & Long-Lasting: Resists compression set, tearing, and aging, extending service life and reducing maintenance costs.
  • Universal Compatibility: Standard circular cross-section and precise dimensions fit most equipment seal grooves, enabling direct, tool-free installation.

Applications:

  • Seals hydraulic system cylinders, valve blocks, and pumps to prevent fluid leakage and maintain pressure stability.
  • Acts as an oil seal in automotive gearboxes and transmissions, protecting lubrication systems and reducing component wear.
  • Provides dust and moisture protection for industrial machinery enclosures, extending component lifespan in harsh environments.
  • Reduces vibration transmission between mating surfaces, improving equipment stability and minimizing operational noise.
  • Ensures leak-proof performance in pneumatic systems, supporting consistent operation of air cylinders and valves.
