## Summary description

Soldered tee fitting VIEGA model 102890 with dimensions 18×18×15 mm, designed for joining copper pipes in plumbing and heating systems. The tee provides a right-angle branch connection to distribute flow between main and branch lines.

## Long description

VIEGA soldered tee fitting 18×18×15 mm model 102890 is a compact copper tee designed for creating a permanent branched connection between copper pipes in plumbing and heating systems. The fitting provides a right-angle branch from a run of 18 mm pipe to a 15 mm branch, enabling reliable distribution of liquids in potable water, heating circuits, and general pipework where a small, space-saving tee is required.
Advantages
The tee is manufactured from copper for good thermal conductivity and corrosion resistance in common water and heating applications. It is intended for soldered joints, ensuring a leak-tight, permanent connection when installed by a qualified fitter. Its compact dimensions reduce space requirements in tight installations and simplify routing of pipework where a reduction from 18 mm to 15 mm is needed.
Suitable for
Potable water distribution in residential and commercial buildings
Heating circuits and radiator connections
General domestic and light commercial copper pipework requiring a branch
Tight or compact installation spaces where reduced branch size is necessary
Key specifications
Material: copper
Connection type: soldered joints (capillary soldering)
Run dimensions: 18 mm × 18 mm
Branch dimension: 15 mm
Configuration: right-angle tee with reduction
Typical applications: potable water and heating systems
How to use
Prepare the copper pipes by cleaning and deburring the ends, then apply appropriate flux to the joint areas. Assemble the tee onto the prepared pipes, ensuring proper alignment of the run and branch. Heat the joint evenly with a suitable torch and apply solder to form a continuous fillet around each connection. Allow the assembly to cool naturally and then inspect for secure, leak-free joints before placing the system into service. Installation should follow local plumbing codes and be performed by a qualified installer.
Usage recommendations
Use lead-free solder and flux compatible with potable water installations. Verify system pressure and temperature ratings of the overall piping layout to ensure compatibility with copper pipework. After soldering, perform a pressure test on the completed circuit to confirm seals and check for any leaks at the tee connection.
