## Summary description

Transition coupling by REHAU designed for soldered connections between pipes with outer dimensions 75 x 6.8 mm and 76.1 x 2.9 mm. The fitting provides a secure metal-to-metal joint suitable for plumbing and HVAC systems where a change in wall thickness or diameter is required. Intended for use in installation, repair and retrofit of pipework requiring a soldered joint.

## Long description

The Copper transition coupling REHAU 75 x 6.8 to 76.1 x 2.9 for soldered connection is a purpose-built fitting that enables a secure metal-to-metal join between two copper pipes with different outer dimensions and wall thicknesses. Designed for plumbing and HVAC installations, this coupling allows installers to connect a thicker-walled pipe (75 x 6.8 mm) to a thinner-walled pipe (76.1 x 2.9 mm) using a soldered joint, ensuring mechanical integrity and reliable fluid flow in systems where a change in pipe geometry is necessary.
Advantages
The coupling delivers a durable soldered connection that resists leakage and maintains strength across differing pipe profiles. Its copper construction provides good thermal and corrosion properties typical of copper piping systems and ensures compatibility with standard soldering procedures. The part is intended to simplify transitions between pipes of closely matched diameters but different wall thicknesses, reducing the need for adapters or complex fabrication on site.
Suitable for
Plumbing installations requiring a change in wall thickness between copper pipes
HVAC systems where soldered copper joints are specified
Repair and retrofit work on existing copper pipe networks
Situations that demand a metal-to-metal transition coupling with soldered sealing
Key specifications
Material: copper
Connection type: soldered (capillary solder joint)
First pipe outer dimension: 75 mm with 6.8 mm wall thickness
Second pipe outer dimension: 76.1 mm with 2.9 mm wall thickness
Application: plumbing and HVAC pipe transitions
How to use
Prepare both pipe ends by cleaning and removing oxidation or debris to ensure proper wetting by solder. Insert the pipe ends into the coupling to the designed stop, apply appropriate flux to the joint area, and heat evenly with a torch until flux activation and solder flow occur. Introduce solder to the joint capillary and allow it to penetrate the interface for a complete seal. After cooling, inspect the joint visually and perform any required pressure or leak tests according to applicable installation standards.
Usage recommendations
Use qualified personnel familiar with soldering copper pipework and follow local codes and safety procedures. Select solder and flux compatible with potable water systems if used in domestic water installations. Ensure adequate ventilation and heat protection for surrounding materials during soldering operations.
