Supplier's note

  1. Technical Breakthroughs:

    • Material Composition: High-carbon steel pistons outperform traditional cast iron by 20% in wear resistance.
    • Precision Engineering: 0.01mm tolerance in piston pins ensures 15% better fuel efficiency.
    • RoHS Compliance: Eliminates hazardous materials, aligning with EU and US environmental standards.

  2. Optimal Version Selection:

    • Base Model: Ideal for routine maintenance in standard-duty engines (e.g., light commercial vehicles).
    • Advanced Model: Suitable for moderate stress applications (e.g., agricultural machinery) with enhanced thermal stability.
    • Pro Model: Designed for heavy-duty engines (e.g., mining equipment) requiring triple the industry-standard chemical resistance. Pair its 52HRC hardness with NBR gaskets to achieve zero leakage in extreme conditions.

*Pro Model exceeds ISO 9001:2015 load capacity benchmarks by 35%.
