Supplier's note

  1. Three Technical Breakthroughs:

    • Material Innovation: The Pro Model’s polymer blend offers 30% higher pressure resistance than industry baselines, enabling use in heavy-duty trucks.
    • Connector Design: Advanced Model connectors feature a 2-stage locking mechanism, reducing leak incidents by 40% in high-vibration environments.
    • Color-Coded Safety: ISO-compliant blue coding aligns with global automotive standards, minimizing cross-contamination risks.

  2. Optimal Version Selection:

    • Base Model: Ideal for standard Peugeot 1.4L diesel engines requiring OEM-equivalent performance.
    • Advanced Model: Recommended for fleet vehicles or改装 applications needing extended temperature and pressure tolerance.
    • Pro Model: The chemical-resistant polymer and extreme-temperature rating make it perfect for off-road or industrial diesel systems. For instance, the Pro’s triple resistance to biodiesel additives ensures longevity in biofuel-heavy markets. Pair its reinforced layers with Peugeot’s high-output turbo engines to prevent fuel line degradation.

Note: Comparative values are relative to industry benchmarks (e.g., SAE J1527 baseline).
