## Summary description

Transition coupling by REHAU for soldered pipe connections, sized 63 x 5.8 mm to 60.3 x 2.9 mm. Designed to join a thicker-walled pipe to a thinner-walled copper or steel pipe via soldered joint. Suitable for plumbing and heating installations where a reliable, mechanically aligned solder connection between different wall-thickness pipes is required.

## Long description

REHAU transition coupling for soldered connection 63 x 5.8 to 60.3 x 2.9 is a purpose-built fitting that connects a thicker-walled pipe (63 mm outer diameter, 5.8 mm wall) to a thinner-walled pipe (60.3 mm outer diameter, 2.9 mm wall) using a soldered joint. The coupling establishes mechanical alignment and a solderable surface for copper or steel pipe ends, enabling a reliable transition between different wall-thickness pipes in plumbing and heating systems. The design is intended for installations where a stable, soldered connection is preferred and where compatibility with standard soldering techniques is required.
Advantages
The transition coupling provides precise alignment between mismatched wall-thickness pipes and offers a solder-compatible surface for creating a durable metal-to-metal joint. It simplifies installation by allowing direct soldering to the thinner-walled pipe while accommodating the thicker-walled counterpart, reducing the need for additional adaptors or complex preparatory work. Constructed to meet common plumbing and heating requirements, the fitting supports leak-resistant connections when soldered correctly and installed according to standard practice.
Suitable for
Connecting a 63 x 5.8 mm pipe to a 60.3 x 2.9 mm copper or steel pipe via soldered joint
Plumbing systems where a transition between different pipe wall thicknesses is required
Heating installations that use soldered joints for pressure-tight connections
Key specifications
Connection type: transition coupling for soldered joint
Larger pipe compatibility: outer diameter 63 mm, wall thickness 5.8 mm
Smaller pipe compatibility: outer diameter 60.3 mm, wall thickness 2.9 mm
Intended pipes: copper or steel pipes suitable for soldering
Application areas: plumbing and heating installations requiring a soldered transition
How to use
Prepare both pipe ends by cleaning and deburring to ensure proper fit and solderability. Slide the transition coupling onto the thicker-walled pipe and position the thinner-walled pipe into the opposite end so that proper overlap is achieved according to installation practice. Apply appropriate flux to the joint surfaces and heat evenly using a suitable torch or soldering tool until the solder flows and forms a continuous fillet. Allow the joint to cool naturally and then inspect for a complete solder fillet and for any signs of gaps or incomplete solder coverage. Test the connection under pressure according to applicable local codes and standards.
Usage recommendations
Use flux and solder compatible with the pipe material; ensure adequate ventilation and follow safety precautions when soldering. Verify that the materials being joined are suitable for soldered connections and that the installation complies with local plumbing and heating regulations.
