Copper Reducing Tee VIEGA 35 x 18 x 35 mm 109899

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.
