## Long description

SiGMA-Li R3220 is a polypropylene (PP) reduction fitting designed for connecting pipes with diameters 32 mm and 20 mm. The reducer provides a secure, leak-resistant transition between different pipe sizes, suitable for plumbing and heating systems where reliable adaptation of pipe diameter is required. Manufactured from polypropylene, the fitting is intended for use with compatible PP piping for water distribution, radiator connections, and repair tasks.
Advantages
The SiGMA-Li R3220 reducer offers chemical and corrosion resistance inherent to polypropylene, combined with dimensional stability for consistent jointing. Its smooth internal surface reduces flow disturbances at the transition point, and the material’s thermal properties support typical domestic hot and cold water applications. The fitting is lightweight, easy to handle during installation, and designed to form tight connections that minimise the risk of leaks when installed according to system requirements.
Suitable for
Connecting 32 mm to 20 mm polypropylene (PP) pipes
Water distribution systems in residential and commercial buildings
Radiator supply and return lines requiring diameter adaptation
Repair and retrofit work where a step-down fitting is needed
Key specifications
Material: polypropylene (PP)
Connection type: reducer for two pipe diameters
Pipe diameters: 32 mm to 20 mm
Application: hot and cold water installations, heating circuits
Surface: smooth internal bore to reduce flow disturbance
How to use
Ensure both pipes are clean, free of debris and cut squarely before installation. Select the appropriate joining method for the system—heat fusion, socket fusion, or mechanical connection—compatible with polypropylene fittings and the existing piping. Insert the pipes into the fitting to the correct depth and complete the joint according to the chosen method and manufacturer guidelines. After assembly, test the system at working pressure to verify leak-free performance.
Usage recommendations
Use the SiGMA-Li R3220 reducer only with compatible polypropylene piping and follow the installation procedures recommended for PP systems. Do not expose the fitting to chemicals or operating conditions beyond the material’s specified limits. For hot-water or heating systems, verify temperature and pressure ratings of the overall system components to ensure compatibility.
