Provides a durable copper connection for soldering or press-fit depending on system compatibility.

## Long description

Copper reducing tee VIEGA 35 x 18 x 35 mm is a metallic plumbing fitting designed to connect three copper pipes, providing a reduced central branch to change pipe diameter within potable water and heating systems. The fitting is intended to create a durable, leak-resistant connection compatible with common joining methods for copper tubing. It is suitable where a 35 mm main line must branch to an 18 mm run while maintaining a reliable copper-to-copper joint.
Advantages
The reducing tee offers robust copper construction that resists corrosion and provides long-term mechanical stability in water and heating installations. Its geometry ensures smooth flow transition between the larger and reduced pipe diameters, while compatibility with standard copper joining techniques allows straightforward installation with soldering or appropriate press-fit tools. The fitting's precise dimensions support predictable hydraulic performance and straightforward integration into existing copper piping networks.
Suitable for
 Branching a 35 mm copper supply line to an 18 mm copper run
 Potable water distribution networks
 Domestic and commercial heating circuits
 Retrofit or new-build copper plumbing systems
Key specifications
 Material: copper
 Pipe connection diameters: 35 mm x 18 mm x 35 mm
 Type: reducing tee
 Suitable joining methods: soldering or press-fit depending on system compatibility
 Application: potable water and heating installations
How to use
Select the correct locations on the existing copper piping where the branch is required, ensuring the system is depressurized and drained before work begins. Prepare pipe ends by cutting square, cleaning, and deburring, then clean mating surfaces of the tee and pipes according to the chosen joining method. For soldered joints, apply flux and heat evenly to form a continuous capillary solder connection. For press-fit systems, follow the press tool manufacturer's instructions to achieve a secure mechanical joint. After installation, inspect joints visually and pressure-test the section to verify integrity before returning the system to service.
Usage recommendations
Use compatible fluxes, solder alloys or press-fit fittings rated for potable water and heating applications. Observe local plumbing codes and manufacturer guidelines for installation, pressure testing, and system commissioning. When working with heat-based joining, protect nearby materials from heat exposure and ensure adequate ventilation. For installations in systems with specific water chemistry or high temperatures, verify copper is suitable or consider alternative materials as required.
