Supplier's note

  1. Three Technical Breakthroughs:

    • Material Innovation: Polypropylene ensures 40% lighter weight than metal couplings while maintaining durability.
    • Seal Design: Ridges reduce leakage risk by 25% compared to flat-surface couplings.
    • Warranty Coverage: 1-year warranty includes accidental damage, exceeding industry norms.

  2. Optimal Version Selection:

    • Base Model: Ideal for residential or light commercial use (e.g., home HVAC systems).
    • Advanced Model: Suitable for industrial water treatment plants needing acid/alkali resistance.
    • Pro Model: Best for extreme environments (e.g., offshore drilling) with its -20°C to 110°C range and triple-certified chemical resistance.

With the Pro version’s enhanced specs, you can safely handle corrosive chemicals while maintaining system integrity. Its UV-stabilized material also ensures longevity in outdoor applications. Pair it with the metering pump for automated dosing in industrial wastewater treatment.

*Based on ISO 10300 standards.
† Meets NSF/ANSI 61 and 3-A Sanitary Standards.
