## Summary description

VIEGA soldered reducing coupling 42 x 35 mm (MPN 106935) is a pipe fitting designed to join two copper or compatible metal pipes of different diameters. The reducing coupling enables a secure, soldered connection between a 42 mm and a 35 mm pipe, providing reliable flow transition in plumbing and heating systems. Suitable for potable water, central heating, and general pipework installations where a permanent sealed joint is required.

## Long description

VIEGA compression reducing coupling 42 x 35 mm soldered is a metal pipe fitting engineered to join a 42 mm copper (or compatible metal) pipe to a 35 mm pipe with a permanent soldered joint. Designed for plumbing and heating systems, this reducing coupling provides a sealed transition between different pipe diameters, ensuring stable flow and mechanical integrity in potable water, central heating and general pipework installations where a soldered connection is preferred.
Advantages
The coupling offers a reliable, leak-resistant joint after proper soldering and is manufactured to consistent dimensional tolerances for straightforward installation. Its reducing form factor allows integration of different pipe sizes without additional adapters, reducing the number of joints and potential leak points. Made from materials compatible with standard copper piping and heating circuits, the fitting supports long-term service in potable water and heating applications when installed according to applicable regulations.
Suitable for
Connecting 42 mm to 35 mm copper or compatible metal pipes
Potable water distribution systems
Central heating and radiator connections
Permanent soldered pipework in domestic and commercial buildings
Key specifications
Type: Reducing soldered coupling for compression-style installation
Connection method: Soldered joint
Materials: Metal compatible with copper piping (suitable for soldering)
Pipe diameters: 42 mm to 35 mm
Application environment: Potable water, heating systems, general pipework
How to use
Prepare pipe ends by cutting squarely, deburring and cleaning the mating surfaces to remove oxidation and contaminants. Apply appropriate flux to both the pipe ends and the inside of the fitting, insert the pipes fully into the coupling, and heat the joint evenly with a suitable torch until solder flows and forms a continuous fillet around the joint. Allow the assembly to cool naturally and then clean residual flux. Follow local codes and manufacturer recommendations for solder type, heating method and safety precautions.
Usage recommendations
Use lead-free solder and flux suitable for potable water systems. Verify compatibility of materials and ensure the work area is well-ventilated. Pressure-test the system after cooling and cleaning to confirm a leak-free installation. For installations in central heating systems, follow system-specific requirements such as corrosion inhibitors and appropriate expansion considerations.
