Supplier's note

  1. Three Technical Breakthroughs:

    • Steel Construction: Withstands pressures up to 200 bar, outperforming aluminum in heavy-duty cycles.
    • Triple Cooling Grooves: Reduces thermal expansion by 18% compared to standard designs.
    • Precision Bore Tolerance: Achieves ±0.003 mm alignment, minimizing wear by 25% in high-RPM applications.

  2. Optimal Version Selection:

    • Base Model: Ideal for routine engine rebuilds in standard-duty trucks or generators.
    • Advanced Model: Suitable for performance-tuned engines (e.g., racing or off-road vehicles) requiring enhanced sealing and heat resistance.
    • Pro Model: Designed for extreme environments (e.g., mining or marine engines) where prolonged thermal and mechanical stress demand premium durability.

Example Use Case: The Pro Model’s 585°C thermal resistance enables safe operation in engines exposed to continuous high-temperature exhaust gases, while its 4-ring design eliminates oil consumption issues in turbocharged setups.
