Supplier's note

1. Key Technical Breakthroughs:

   • Material Diversity: FKM in the Pro Model offers triple the oil resistance of NBR, ideal for heavy machinery.
   • Temperature Tolerance: The Pro’s -40°C to +200°C range outperforms industry benchmarks by 30%, enabling use in Arctic or high-heat zones.
   • Certification Expansion: UL certification for the Pro Model ensures compliance with global industrial safety protocols.

2. Optimal Version Selection:

   • Base Model: Suitable for general industrial use (e.g., HVAC systems) where standard chemical exposure and temperatures suffice.
   • Advanced Model: Preferred for outdoor equipment (e.g., solar panels) needing UV resistance and wider temperature adaptability.
   • Pro Model: Essential for extreme environments (e.g., aerospace, offshore drilling) requiring unmatched chemical/thermal stability.

*Pro Model’s UL certification and expanded temperature range enable safe deployment in oil rigs or aerospace applications where traditional materials fail. Pair FKM’s chemical resistance with silicone’s flexibility to create a seal that withstands corrosive fluids and mechanical stress.
