Advantages

  • Excellent Oil Resistance: Nitrile rubber material exhibits strong tolerance to mineral oils, hydraulic fluids, and other petroleum-based media, making it suitable for oil-contact applications.
  • Balanced Elasticity & Sealing: The A75K hardness formula balances elasticity and structural support, ensuring reliable sealing in both static and dynamic operating conditions.
  • Wide Temperature Range: Operates stably between -40°C and 120°C, meeting the temperature requirements of most industrial and automotive scenarios.
  • Wear & Aging Resistance: Boasts good tear resistance and compression set resistance, resisting hardening and failure over long-term use, reducing maintenance costs.
  • Universal Compatibility: Standard dimensions and cross-section design allow direct replacement of original seals in most equipment, eliminating the need for additional machining.

Applications:

  • Acts as an oil seal in automotive engines and gearboxes to seal engine oil and gear oil, preventing leakage and ensuring lubrication efficiency.
  • Seals valve blocks and cylinders in hydraulic systems to prevent hydraulic oil leakage, maintaining system pressure stability and ensuring precise equipment operation.
  • Provides dynamic sealing for industrial pumps and compressors, reducing vibration transmission and improving equipment stability and service life.
  • Serves as a waterproof and dustproof seal in small machinery and household appliances, protecting internal components from external contaminants.
  • Fits cylinders and connectors in pneumatic systems to prevent compressed air leakage, ensuring responsive speed and operational efficiency of pneumatic components.
