VIEGA reducing tee 54 x 35 x 54 mm soldered fitting 117818

VIEGA reducing tee 54 x 35 x 54 mm soldered fitting 117818 is a solder-type copper tee designed to form a permanent branch connection between three pipes, with a reduction from 54 mm to 35 mm in the side outlet. The fitting is intended for use in plumbing and heating systems where durable, leak-tight soldered joints are required. Its geometry allows straightforward integration into existing copper or compatible metal piping runs for distribution, branching and retrofit tasks.

Advantages

The soldered construction provides a stable, permanent joint resistant to mechanical stress and internal pressure when correctly installed. The reducing tee enables a smooth transition between different pipe diameters within the same run, reducing turbulence and flow disruption at the branch. Manufactured by VIEGA, the fitting conforms to typical industry materials and workmanship expectations for copper solder joints, facilitating reliable system performance and long service life when used with appropriate solder and flux.

Suitable for

• Plumbing distribution lines and branch connections
• Hot and cold water installations
• Heating system pipework and radiators
• Retrofit or modification of existing copper piping

Key specifications

• Type: reducing tee with one reduced branch
• Main pipe diameter: 54 mm
• Branch pipe diameter: 35 mm
• Material: copper or copper-alloy suitable for soldering
• Connection method: soldered joint
• Application: potable water, heating and general fluid distribution (subject to local codes)

How to use

Prepare pipe ends by cutting square and removing burrs, then clean the fitting and pipes with an appropriate abrasive and flux to ensure proper wetting. Assemble the tee onto the prepared pipes and apply solder evenly around each joint while heating to the appropriate temperature for the chosen solder type. Allow joints to cool naturally and inspect for complete fillets and absence of voids or gaps. Pressure-test the installation in accordance with local regulations and standards before commissioning.

Usage recommendations

Use solders and fluxes compatible with copper and approved for potable water if applicable. Follow applicable building codes and manufacturer guidance for maximum operating pressures and temperatures. For best results, employ trained personnel or certified installers for soldered joints and pressure testing.
