## Long description

SiGMA-Li R2520 25×20 mm PVC/PP plumbing fitting is a compact reducer designed to connect 25 mm and 20 mm plastic pipes in water supply and drainage systems. Made from polypropylene (PP), this fitting provides a secure, corrosion-resistant transition between different pipe diameters.

Key specifications
Material: polypropylene (PP)
Connection sizes: 25 mm to 20 mm
Type: concentric reducer for plastic pipe systems
Application: water supply and drainage
Construction: single-piece molded fitting
How to use
Before installation, verify pipe diameters and ensure pipe ends are clean, smooth and free of burrs. Push-fit or solvent-weld techniques may be used depending on the piping system and local practice; follow the recommendations for joining PP fittings applicable to your system. Insert the 25 mm pipe into the larger end and the 20 mm pipe into the smaller end with full engagement to ensure a secure connection. After installing, perform a pressure or leak test according to local codes to confirm sealing and alignment.
Usage recommendations
Use the reducer in systems within the manufacturer’s recommended temperature and pressure range for polypropylene fittings. Avoid exposure to open flame and prolonged UV irradiation; if the installation is outdoors, consider additional protection or compatible UV-stable components. For long runs or systems with significant mechanical load, provide appropriate support and avoid point loads on the fitting.
