## Summary description

Reducer elbow SiGMA-Li KR2016 is a PP‑R plumbing fitting with 20×16 mm diameters designed to connect pipes of different sizes at a 90° angle. Made of polypropylene random copolymer (PP‑R), it provides corrosion resistance, chemical stability and suitability for potable water and heating systems. Used for reliable directional transitions in residential and commercial piping.

## Long description

Reducer elbow SiGMA-Li KR2016 20×16 mm PP-R plumbing fitting is a 90° angled connector designed to join pipes of different diameters in water supply and heating installations. Manufactured from polypropylene random copolymer (PP‑R), this reducer elbow offers chemical stability, resistance to corrosion and long-term dimensional stability. The fitting is intended for reliable directional transitions between 20 mm and 16 mm piping where a compact right‑angle change of diameter is required.
Advantages
The PP‑R material ensures durability and resistance to most common chemicals found in potable water and heating systems while maintaining low thermal conductivity. Its one‑piece molded construction provides leak‑resistant joints when welded by appropriate fusion methods. The compact 90° design saves installation space and facilitates neat routing of pipes in confined areas. The fitting is compatible with standard PP‑R piping and typical installation tools used for fusion joining.
Suitable for
 Domestic cold and hot potable water distribution
 Residential and small commercial heating circuits
 Transitions between 20 mm and 16 mm PP‑R pipelines in tight installations
 Plumbing repairs and retrofits where a right‑angle reduction is needed
Key specifications
 Material: polypropylene random copolymer (PP‑R)
 Connection type: socket fusion (butt/weld depending on system)
 Angle: 90 degrees
 Nominal diameters: 20 mm to 16 mm
 Application temperature: suitable for typical potable water and heating temperatures (refer to system norms for limits)
How to use
Prepare the PP‑R pipe ends by cutting square and cleanly, removing any burrs or debris. Align the 20 mm and 16 mm pipe ends with the corresponding sockets of the reducer elbow. Use the appropriate socket fusion or butt welding equipment for PP‑R materials according to the tool manufacturer’s instructions and local standards. After welding, allow the joint to cool undisturbed for the recommended time before applying pressure or testing the system. Inspect the welded joints for correct penetration and absence of visible defects.
Usage recommendations
Use correct fusion parameters (temperature and time) for PP‑R material and the specific pipe wall thickness. Avoid exposure to direct sunlight for extended periods during storage and follow local regulations for potable water and heating installations. For pressure or temperature limits, consult applicable standards and system designers.
