## Long description

Reducer fitting SiGMA-Li R3225 is a concentric polypropylene (PP) connector designed to join 32 mm and 25 mm plastic pipes in plumbing and drainage systems. It provides a smooth step-down transition between diameters while maintaining flow continuity and a compact footprint. The fitting is suitable for use in potable water, wastewater and general domestic installations where a reliable plastic connection between different pipe sizes is needed.
Advantages
The PP construction offers chemical resistance, low weight and corrosion-free service life, making the fitting suitable for long-term use in moist and chemically active environments. As a concentric reducer, it ensures axial alignment of connected pipes and reduces turbulence at the diameter change. The simple geometry and smooth interior support straightforward installation and predictable hydraulic behaviour.
Suitable for
 Connecting 32 mm to 25 mm plastic pipes in domestic plumbing
 Potable water distribution and return lines
 Wastewater and drainage systems
 Repair or modification of existing plastic pipe networks
Key specifications
 Material: polypropylene (PP)
 Connection type: concentric step-down reducer
 Outlet diameters: 32 mm → 25 mm
 Suitable media: potable water, wastewater, general domestic fluids
 Operating environment: indoor and protected outdoor installations
How to use
Select the appropriate pipe ends, ensuring they are clean, dry and free of burrs. Fit the 32 mm pipe into the larger end of the reducer and the 25 mm pipe into the smaller end, using the recommended jointing method for the pipe system (e.g., solvent welding, mechanical socket, or push-fit) compatible with PP fittings. Ensure axial alignment and fully seat each pipe to the stop. After assembly, verify the joint integrity by conducting a pressure or leak test according to applicable local standards.
Usage recommendations
For reliable performance, store fittings away from direct sunlight and extreme temperatures prior to installation. Use appropriate sealing or joining materials specified for polypropylene systems and follow local plumbing codes for potable water or wastewater applications.
