## Summary description

Copper reducing coupling VIEGA 28/22 mm (model 102111) — a solderable plumbing fitting designed to join copper pipes of 28 mm and 22 mm diameters. Provides a mechanical and leak-resistant transition between different pipe sizes for water or heating systems. Suitable for residential and commercial installations where durable copper connections and corrosion resistance are required.

## Long description

Copper reducing coupling VIEGA 28/22 mm (muff) model 102111 is a solderable plumbing fitting designed to join copper pipes of different diameters. It creates a secure transition between a 28 mm and a 22 mm copper tube and is intended for use in water supply and heating circuits where durable metallic connections and corrosion resistance are required.
Advantages
The coupling is made of copper, which ensures good thermal conductivity and resistance to corrosion in typical potable water and heating environments. Its solderable design provides a permanent, leak-resistant joint when installed correctly by soldering or brazing. The simple cylindrical shape allows easy alignment of pipes and reduces the need for additional adapters or sealing elements.
Suitable for
 Connecting 28 mm to 22 mm copper pipes in domestic plumbing
 Repairing or extending heating circuits that use copper tubing
 Hot and cold water distribution systems in residential and light-commercial buildings
 Applications requiring a corrosion-resistant metal joint
Key specifications
 Material: copper
 Connection type: solderable (muff / socket)
 Compatible pipe diameters: 28 mm and 22 mm
 Shape: reducing cylindrical coupling
 Typical applications: potable water and heating systems
How to use
Prepare pipe ends by cutting square and removing burrs and oxides. Clean the outer surface of the male pipe ends and the inner surfaces of the coupling with an appropriate abrasive or chemical cleaner suitable for copper to ensure proper solder adhesion. Apply flux to the joint surfaces, insert the pipes fully into the coupling until they bottom out, and heat the joint evenly with a suitable torch. Feed solder into the heated seam until a continuous fillet forms around both pipe connections. Allow the joint to cool naturally and then inspect for a uniform solder bead and signs of leaks before placing the system into service.
Usage recommendations
Use appropriate personal protective equipment and follow local codes for potable water and heating installations. Select solder and flux that are compatible with copper piping and approved for potable water if used for drinking water systems. Ensure the system is pressure-tested after installation and follow recommended temperature and pressure limits for copper pipework.
