Reducer fitting SiGMA-Li R5032, 50×32 mm PVC plumbing reducer

SiGMA-Li R5032 is a reducer fitting designed for plumbing systems to connect 50 mm pipes to 32 mm pipes. Manufactured from PVC, the fitting provides a compact solution for diameter adaptation in water supply and drainage installations. Its geometry allows a secure mechanical transition between larger and smaller lines while keeping the installation profile small, which is useful in confined spaces and standard residential or commercial plumbing layouts.

Advantages

The reducer fitting offers reliable mechanical connection without the need for complex tools, and PVC construction delivers corrosion resistance and low weight. Its standardized outer dimensions ensure compatibility with common pipe types and enable easy integration into existing systems. The compact shape simplifies routing in tight areas and reduces the amount of additional fittings required for diameter changes.

Suitable for

• Transitioning from 50 mm to 32 mm pipes in water supply networks
• Drainage and waste systems requiring diameter adaptation
• Plumbing repairs and retrofits in residential and commercial buildings
• Confined or space-limited installations where a compact reducer is needed

Key specifications

• Material: PVC
• Connection sizes: 50 mm to 32 mm
• Function: diameter reduction/pipe transition
• Typical application: water supply and drainage systems
• Design: compact, low-profile reducer

How to use

Prepare the pipe ends by cutting squarely and deburring to ensure proper seating. Clean mating surfaces and apply an appropriate PVC solvent cement or sealing method recommended for the pipe system being used, following manufacturer instructions for the adhesive or sealing system. Insert the smaller and larger pipes into the respective ends of the reducer until fully seated and allow the joint to cure according to adhesive specifications or secure with the chosen mechanical sealing method. Verify alignment and check for leaks once the joint has set and the system is pressurized.

Usage recommendations

Use the fitting in systems compatible with PVC components and within the pressure and temperature limits specified for the selected pipe and adhesive system. Avoid exposure to chemicals or temperatures outside the material limits. For permanent, pressure-bearing joints follow solvent-weld or approved mechanical joining procedures and test the system after installation.
