Supplier's note

1. Technical Breakthroughs:

   • Material Innovation: 316 stainless steel in Pro models offers 40% higher corrosion resistance than standard steel, extending lifespan in acidic fuel environments.
   • Bend Optimization: Patented bend design reduces pressure drop by 25% compared to straight hoses, improving fuel efficiency.
   • Certification Compliance: CE certification ensures seamless integration into EU-approved Caterpillar machinery.

2. Version Selection Guide:

   • Base Model: Ideal for standard excavators or loaders with moderate pressure needs (e.g., 300 bar systems).
   • Advanced Model: Recommended for mid-sized bulldozers requiring cold-weather resilience (-40°C) and 20% higher pressure tolerance.
   • Pro Model: Best for high-horsepower machinery (e.g., mining trucks) needing triple-industry-standard chemical resistance and 390 bar pressure capacity. With its premium wall thickness, it minimizes leakage risks in abrasive environments.
