Copper Reducing Tee VIEGA 28x15x28 mm - model 101619

The VIEGA Copper Reducing Tee 28x15x28 mm (model 101619) is a three-way fitting designed for copper piping systems where a reduction in branch diameter is required. It connects two 28 mm main lines with a 15 mm branch, enabling smooth transitions between different pipe sizes in potable water, heating circuits and general copper installations. The tee is manufactured to suit standard soldered or brazed jointing methods used in professional plumbing and heating work.

Advantages

This copper reducing tee provides reliable, leak-resistant connections when properly installed by soldering or brazing. Its material properties ensure compatibility with potable water and heating media, offering good thermal conductivity and corrosion resistance typical of copper fittings. The compact design allows integration into tight spaces while maintaining flow characteristics appropriate for reduced-branch installations.

Suitable for

• Potable water distribution networks requiring a 15 mm branch from 28 mm mains
• Residential and commercial heating circuits with mixed pipe diameters
• General copper plumbing systems where a reduced-size outlet is needed

Key specifications

• Material: copper
• Connection configuration: reducing tee (two equal mains, one smaller branch)
• Connection dimensions: mains 28 mm, branch 15 mm
• Jointing method: suitable for soldering/brazing
• Application: potable water and heating systems

How to use

Prepare tubing ends by cutting square and cleaning with an appropriate abrasive or flux brush to expose bright copper. Apply flux to joint surfaces where recommended, insert pipes fully into the fitting, and perform soldering or brazing according to applicable codes and procedures. Allow joints to cool and inspect visually, then pressure-test the system to verify leak-free performance before commissioning.

Usage recommendations

Use compatible solder and flux materials approved for potable water or heating applications, and follow local plumbing standards for brazing temperatures and testing. Ensure proper support and alignment of connected pipes to avoid stress on the fitting and maintain system longevity.
