Supplier's note

  1. Technical Breakthroughs:

    • Eco-Friendly Material Blend: Aluminum reduces weight by 20% vs. all-brass fittings.
    • Solder-Free LoKring: Eliminates welding risks, cutting installation time by 30%.
    • Commercial-Grade Pressure Tolerance: The Pro Model’s 300 PSI rating exceeds industry benchmarks by 50%, ideal for industrial refrigeration.

  2. Optimal Version Selection:

    • Base Model: Suitable for residential HVAC repairs where standard pressure (≤200 PSI) and moderate temperatures are sufficient.
    • Advanced Model: Targets commercial kitchens or cold storage systems needing enhanced corrosion resistance and wider temperature tolerance.
    • Pro Model: Designed for heavy-duty industrial use (e.g., ammonia-based refrigeration) where extreme pressure and sub-zero temperatures are standard.

With the Pro version’s 300 PSI rating and -40°C to 200°C range, technicians can safely handle high-pressure refrigerants in extreme environments. Pair its stainless steel material with the LoKring’s leak-proof seal to ensure zero downtime in critical systems.
