Reducer Tee VIEGA 28x22x28 mm, model 5130R282228, copper plumbing fitting

VIEGA reducer tee 28x22x28 mm is a copper plumbing fitting designed to connect three pipe runs where the central branch reduces the diameter. The fitting provides a reliable junction between two 28 mm main runs and a 22 mm reduced outlet, making it suitable for water distribution and heating systems that require a change in pipe size while maintaining a continuous copper line.

Advantages

The reducer tee is manufactured from copper to ensure corrosion resistance and thermal conductivity suitable for potable water and heating circuits. Its precise dimensions and smooth internal transitions reduce flow disturbances and pressure loss at the branch point. The component is compatible with standard copper joining methods and offers a compact solution for system layouts requiring a reduction in diameter without additional adapters.

Suitable for

• Domestic and commercial water supply installations
• Central heating systems and radiators
• Retrofit work where a 28 mm run must feed a 22 mm branch
• Hydronic systems and boiler connections

Key specifications

• Material: copper
• Nominal sizes: main runs 28 mm, reduced branch 22 mm
• Type: reducer tee (three-way fitting with reduced outlet)
• Application: water distribution and heating systems
• Connection method: compatible with soldering, brazing, or approved mechanical joining for copper tubing

How to use

Select appropriate copper tubing of the specified diameters and prepare tube ends by cleaning and degreasing. Position the reducer tee so the 28 mm ports align with the main runs and the 22 mm port aligns with the branch. Assemble using the recommended joining method for copper fittings—such as soldering or brazing—following applicable local codes and manufacturer instructions. After joining, pressure-test the system to verify joint integrity and check for leaks before placing the system into regular operation.

Usage recommendations

Ensure compatibility with the system's pressure and temperature ratings and follow local plumbing codes. Use proper flux and heating techniques to achieve leak-free joints, and consider insulating exposed copper runs in heating systems to reduce heat loss.
