SMART CONNECTION
Weld-free copper pipe joint solutions (Daikin Gas Tight Joint) and modern Header Packs for safe, fast, high-level VRV installation.
Daikin Gas Tight Joint (DGT)
Daikin Gas Tight Joint (DGT) is a copper pipe connection used without a brazing process (brazeless), designed to make on-site installation easier, faster, and safer.
Fast & Weld-Free
Fast installation without welding tools (Brazeless).
No Fire or Smoke Risk
Prevents fire risks and excessive smoke at the job site.
High Pressure Resistant
Operating pressure up to 4.3 MPa & burst pressure > 18.0 MPa.
Leak-Free
Precision-guaranteed joint quality to prevent refrigerant leaks.
DGT Models & Specifications
Diameter sizes and official Daikin technical standards for Gas Tight Joint.
General Technical Specifications
How to Install DGT
Easy and safe brazeless installation steps according to Daikin's official guide.
Pipe Cutting & Cleaning
Cut the copper pipe squarely (90°) using a pipe cutter. Thoroughly remove copper burrs (deburring) from the inside and outside of the pipe.
Daikin Header Pack
Header Pack is a modern manifold connector system for VRV refrigerant pipe branches. It enables highly neat pipe branching, maximum work efficiency, and easy connection of VRV indoor units.
Exceptional Neatness
Neat, precisely arranged branch piping installation in VRV systems.
Reduce Weld Points by 70%
Reduces the number of brazed joints and minimizes potential leaks.
Fast Installation
Connecting to indoor units is far more practical & efficient.
Space & Cost Saving
Saves ceiling installation space and piping cost per meter.
Header Pack Models & Capacities
Branch manifold model options for VRV systems of various scales.
Suitable for branching to 4 VRV indoor units
Suitable for branching to 6 VRV indoor units
Suitable for branching to 8 VRV indoor units
Suitable for branching to 10 VRV indoor units
Header Pack Installation & Connection Diagram
The Header Pack is placed between the VRV Outdoor unit and the row of Indoor units. Centralized connections make servicing and piping layout in the building's ceiling area easier.
