• Low expansion rate: When the brake fluid pressure surges, the pipe diameter expansion rate is less than 0.3%, ensuring the braking response.
• Low friction inner wall: The flow resistance of the steering oil is small, making the power-assisted steering more responsive.
• Interface leak-proof design: Combined with a silicone sealing ring, the fit between the interface and the water tank and water pump reaches 99.8%.
• Suitable for complex layouts: The minimum bending radius is up to 12mm, suitable for narrow engine compartments and steering pipelines.
• High-temperature resistant coolant: Can withstand coolant temperatures of 120°C to 150°C, and will not soften when in contact with antifreeze for a long time.1
