## Summary description

Soldered reducing coupling by VIEGA, size 35 x 22 mm (model 109738). Designed for joining copper pipes of different diameters using capillary soldering. Provides a reliable mechanical and hydraulic connection in plumbing and heating systems. Suitable for potable water, central heating, and other copper pipe installations where a reduction from 35 mm to 22 mm is required.

## Long description

Copper reducing coupling VIEGA 35 x 22 mm soldered, model 109738 is a soldered fitting designed to join copper pipes of different diameters by capillary soldering. The fitting provides a compact, low-profile connection that transitions from a 35 mm pipe to a 22 mm pipe and is intended for use in potable water and central heating systems. Manufactured by VIEGA, the coupling is produced from copper material suitable for standard plumbing and heating installations where a reliable mechanical and hydraulic joint is required.
Advantages
The soldered reducing coupling offers a secure, permanent joint when properly installed by capillary soldering, ensuring minimal risk of leakage and good hydraulic performance. Its copper construction provides corrosion resistance appropriate for potable water and heating circuits, and the reduced-profile design simplifies installation in confined spaces. The coupling is compatible with standard copper tubing and supports conventional soldering techniques commonly used by plumbers and heating technicians.
Suitable for
 Reducing a copper pipeline from 35 mm to 22 mm in potable water systems
 Step-down connections in central heating and hot water circuits
 Retrofit or renovation work where existing copper pipes of differing diameters must be joined
 Applications requiring a permanent soldered copper-to-copper connection
Key specifications
 Material: copper
 Connection method: capillary soldering (soldered joint)
 Sizes: 35 mm to 22 mm reducing coupling
 Application media: potable water, central heating fluids compatible with copper
 Operating environment: plumbing and heating systems
How to use
Prepare the pipe ends by cutting square, deburring, and cleaning the external and internal surfaces to remove oxidation, oils, and dirt. Apply appropriate flux to the joint area, assemble the 35 mm and 22 mm pipe ends into the coupling, and heat evenly with a suitable torch until the flux becomes active and solder flows into the capillary gap. Allow the joint to cool naturally, then inspect the solder fillet for complete coverage and integrity. After cooling, test the system according to local plumbing regulations to confirm there are no leaks.
Usage recommendations
Use qualified personnel familiar with capillary soldering techniques and follow applicable safety procedures, including adequate ventilation and heat protection. Select solder and flux compatible with potable water systems when installing on drinking water lines, and observe local codes for water and heating installations.
