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.
