This video introduces the high conductivity copper HVAC branch fitting for modern temperature control systems. It uses high grade deoxidized copper material with excellent heat transfer performance to improve energy efficiency. The precision cold forming process strengthens the internal structure and enhances mechanical durability. The multi port design with central inlet and symmetrical outlets ensures stable and even fluid delivery. Optimized internal flow channels reduce turbulence and pressure loss during operation. The surface protective treatment improves corrosion resistance for different working environments. The fitting can bear high pressure and frequent temperature changes without damage. Each product experiences complete quality inspection including dimensional accuracy pressure test and leak check. It is a reliable component to improve the stability and service life of HVAC and refrigerant pipeline systems
