Copper tee fitting VIEGA 28x28x28 mm model 345969

Copper tee fitting VIEGA 28x28x28 mm model 345969 is a three-way connector designed to join three equal-diameter copper pipes in plumbing, heating and potable water systems. Made from copper, the fitting offers corrosion resistance and stable mechanical strength for creating T-joints in pipelines where a 28 mm branch and run are required. The component is intended for use with soldering or other compatible joining methods in accordance with applicable installation standards.

Advantages

The copper construction ensures long-term resistance to corrosion and good thermal conductivity for heating applications. Dimensional uniformity simplifies alignment and reduces installation time when connecting three equal pipes. The simple geometry and smooth internal surfaces help maintain flow characteristics while providing a mechanically robust joint when correctly joined by soldering or approved methods.

Suitable for

• Domestic and commercial potable water distribution
• Central heating and radiator circuits
• Plumbing repairs and new pipework installations
• Hydronic systems requiring 28 mm copper branches

Key specifications

• Material: copper
• Connection type: 3-way tee for joining three equal pipes
• Nominal diameter: 28 mm for run and branch
• Application: water, heating and potable systems
• Joining methods: suitable for soldering and compatible installation techniques

How to use

Prepare pipe ends by cutting square and cleaning the surfaces to the extent required by the chosen joining method. Assemble the pipes into the tee fitting, ensuring correct alignment and insertion depth. Perform soldering or the selected compatible joining procedure following manufacturer and local installation standards, and allow adequate cooling and inspection time. After joining, pressure-test the assembled system in line with applicable codes to verify leak-free operation.

Usage recommendations

Use appropriate flux and solder materials recommended for copper fittings, and follow safety practices for heating and soldering. Ensure compatibility of the chosen joining method with potable water installations if used for drinking water. For system longevity, avoid exposure to dissimilar metals without proper isolation to reduce galvanic corrosion risk.
