Supplier's note

  1. Three Breakthroughs:

    • Material Synergy: The brass-plastic combination reduces weight by 20% compared to all-metal valves while maintaining structural integrity.
    • Seal Innovation: Teflon seals in the Pro model offer 50% better chemical resistance than standard rubber, enabling use with aggressive fluids.
    • Certification Compliance: Full EPR/France/Germany coverage simplifies waste management for EU automotive recyclers.

  2. Version Selection Guide:

    • Base Model: Ideal for standard automotive repairs (e.g., Golf V, Passat) where pressure ≤200 PSI and ambient temps stay within -20°C to 120°C.
    • Advanced Model: Suitable for industrial HVAC systems or colder climates (e.g., Nordic automotive fleets) needing -30°C operation.
    • Pro Model: Required for heavy-duty industrial machinery or chemical plants where extreme temps (up to 200°C) and corrosive fluids are present.

*Pro Model’s 300 PSI rating exceeds ISO 10378 industrial valve benchmarks by 25%.
