Supplier's note

  1. Technical Breakthroughs:

    • Material Innovation: The Pro Model’s fluororubber compound offers triple the chemical resistance of industry benchmarks, enabling safe use with corrosive fluids.
    • Pressure Tolerance: Advanced and Pro versions exceed standard hydraulic systems’ requirements by 15–30%, ensuring reliability in heavy-duty applications.
    • Temperature Range: The Pro Model’s -40°C to 150°C tolerance caters to extreme environments, such as Arctic construction or desert mining.

  2. Version Selection Guide:

    • Base Model: Ideal for standard hydraulic systems in moderate environments (e.g., general construction).
    • Advanced Model: Suitable for harsh conditions like mining or offshore drilling, where extended temperature and pressure ranges are critical.
    • Pro Model: Required for applications involving aggressive chemicals (e.g., acid-resistant pumps) or extreme temperatures. With its triple chemical resistance, the Pro Model ensures zero leakage even in corrosive scenarios.

*Comparative benchmarks based on ISO 37 standard for hydraulic seal performance.
