Supplier's note

  1. Technical Breakthroughs:

    • Composite Material: The stainless steel core with nitrile rubber provides dual benefits of structural rigidity and flexible sealing.
    • Precision Engineering: Custom-fit cutouts ensure alignment accuracy, reducing installation errors.
    • Enhanced Thermal Resistance: The Pro Model’s 390°C tolerance triples industry benchmarks, enabling safe operation in extreme environments.

  2. Version Selection Guide:

    • Base Model: Ideal for standard-duty Cummins engines requiring reliable sealing under normal operating conditions.
    • Advanced Model: Recommended for engines with moderate stress, such as frequent high-load cycles.
    • Pro Model: Designed for heavy-duty applications (e.g., mining, construction vehicles) where extreme temperatures and pressures are routine. With triple the chemical resistance of traditional gaskets, it prevents corrosion and maintains seal integrity even in harsh environments. Pair its thicker material with high-compression diesel engines to ensure long-term durability.
