Supplier's note

1. Three Technical Breakthroughs:

   • Material Upgrades: The Pro Model’s 400°C thermal resistance (vs. industry standard 350°C) enables safe operation in extreme environments.
   • Precision Fit: CNC-machined pistons ensure a 0.01mm tolerance, reducing friction losses by 20% compared to traditional models.
   • Extended Lifespan: The Pro Model’s 10,000-hour durability is 60% higher than Base Model, ideal for 24/7 construction operations.

2. Optimal Version Selection:

   • Base Model: Suitable for routine maintenance of light-duty machinery (e.g., compact tractors) with standard operating conditions.
   • Advanced Model: Recommended for medium-duty applications (e.g., excavators) requiring enhanced durability and compliance with API standards.
   • Pro Model: Designed for heavy machinery (e.g., large loaders) operating in extreme temperatures or corrosive environments. Its SAE-certified components ensure triple the chemical resistance of industry benchmarks, safeguarding against abrasive dust and oil contamination.

With the Pro Model’s 400°C heat resistance, you can safely operate engines in high-temperature regions. The Advanced Model’s API certification ensures compatibility with premium lubricants, reducing downtime. Choose wisely based on your machinery’s workload and environmental demands.
