## Long description

VIEGA reducing tee 18x15x15 mm N27 is a copper pipe fitting engineered to create a branch with a reduced outlet in potable water and heating systems. The fitting connects an 18 mm inlet to two 15 mm outlets, providing a compact, corrosion-resistant junction for changes in pipe diameter. It is intended for use with compatible copper pipework and can be joined by the installation methods recommended by VIEGA for this product.
Advantages
The copper construction ensures good thermal conductivity and long-term resistance to corrosion in typical plumbing environments. The reducing tee design allows a smooth transition between diameter sizes while maintaining reliable flow distribution. Its compact form factor simplifies installation in confined spaces and supports standard joining techniques used in copper plumbing.
Suitable for
 Branching potable water supply lines
 Creating feed lines for radiators or heating circuits

 Domestic and light commercial plumbing installations
Key specifications
 Material: copper
 Dimensions: inlet 18 mm, outlets 15 mm
 Connection type: socket for soldering or approved VIEGA joining methods
 Application fluids: potable water and heating systems
 Suitable for indoor plumbing and heating installations
How to use
Prepare compatible copper pipes by cutting squarely and deburring the ends. Ensure surfaces are clean and free of oxidation or contaminants before joining. Fit the 18 mm pipe into the main socket and insert the two 15 mm branch pipes into the side sockets. Join the connections following VIEGA's specified method for this fitting—commonly soldering or another approved technique—observing appropriate flux, solder or filler material, and heating procedures. After joining, inspect joints visually for complete fill and test the system under working pressure to verify leak-tightness.
Usage recommendations
Follow local plumbing codes and VIEGA installation guidelines when selecting joining methods and materials. Use appropriate safety equipment when soldering or heating fittings, and pressure-test the system after installation. For installations involving drinking water, use potable-grade flux and cleaning procedures to avoid contamination.
