Copper Reducing Tee VIEGA 35×28×35 mm - model 105808

Copper reducing tee VIEGA 35×28×35 mm is a three-way plumbing fitting designed to join two equal-diameter runs with a smaller branch in copper piping systems. Manufactured by VIEGA, this fitting provides a durable copper-to-copper connection for potable water and heating applications. The reducing tee enables a smooth transition from two 35 mm lines to a 28 mm branch while maintaining flow characteristics and mechanical stability in residential and commercial installations.

Advantages

The copper construction offers corrosion resistance, long service life and reliable thermal conductivity useful in hot water and heating circuits. The design ensures secure joining with standard copper soldering or compatible joining methods, producing leak-resistant connections when installed correctly. Its dimensional configuration simplifies system design when a reduced branch is required without introducing plastic transition components.

Suitable for

• Domestic potable water distribution
• Central heating systems and radiator branches
• Commercial plumbing installations requiring copper connections
• Renovation projects where pipe size reduction is needed

Key specifications

• Material: copper
• Configuration: reducing tee (two equal runs, one reduced branch)
• Run diameters: 35 mm
• Branch diameter: 28 mm
• Application: water and heating systems

How to use

Prepare the copper pipes by cutting squarely and deburring the ends. Clean the fitting and pipe ends to remove oxides and contaminants, then apply the appropriate soldering flux if using capillary soldering. Assemble the tee onto the pipes, ensuring full insertion to the shoulder, and perform soldering or another compatible joining method according to accepted plumbing practice and local regulations. Allow the joint to cool and inspect for continuity and leaks before placing the system into service.

Usage recommendations

Use compatible joining techniques (e.g., capillary soldering or approved mechanical connectors) and follow manufacturer and local codes. Verify suitability for potable water or heating circuits and perform pressure testing after installation. Avoid mixing dissimilar metals without proper dielectric fittings to prevent galvanic corrosion.
