Key features

  • 1. Corrosion-Resistant Copper Material

    • With corrosion-resistant copper construction, ensure long-lasting durability in harsh HVAC environments. Copper outperforms plastic alternatives in resisting rust and degradation, even under high humidity or temperature fluctuations.*

  • 2. Y & T Branch Design for Flexible Flow Management

    • With Y-branch and T-branch configurations, easily customize flow distribution and splitting for precise system integration. The Y-fitting balances tri-directional airflow, while the T-fitting streamlines splitting/combining flows in complex duct networks.

  • 3. High-Pressure & Temperature Performance

    • With rated support for commercial-grade pressure and temperature ranges, maintain reliability in demanding HVAC systems. Designed to handle the rigorous demands of VRV VRF systems, surpassing residential-grade fittings in durability.*

  • 4. Commercial-Grade Scenario Adaptability

    • Designed for continuous commercial use, these fittings ensure stable performance in 24/7 HVAC operations. The Y-branch’s even flow distribution optimizes cooling/heating efficiency in large-scale installations.

  • 5. Manual & Automated Welding Compatibility

    • With dual compatibility for manual labor and automated welding, simplify installation in both small-scale repairs and large commercial projects. Reduces downtime compared to fittings requiring specialized tools.*

  • Notes:

    • Comparative hints are included where material advantages (e.g., copper vs. plastic) or versatility (manual/automated welding) are implied.
