## Long description

VIEGA 25 x 16 plastic gray reducer coupling is a compact pipe connector designed to join 25 mm and 16 mm pipes in plumbing and heating systems. Made from durable plastic, the reducer provides a smooth transition between different pipe diameters while maintaining flow integrity. It is suitable for potable water and heating circuits where a plastic coupling with reliable sealing and corrosion resistance is required.
Advantages
The reducer coupling offers a space-saving design and low weight compared with metal alternatives, simplifying handling and installation. Its plastic construction resists corrosion and scaling, reducing maintenance needs in potable water and heating applications. The product enables a straightforward diameter change without complex fittings, ensuring a stable connection between 25 mm and 16 mm pipework.
Suitable for
 Connecting 25 mm supply or distribution pipes to 16 mm branch lines
 Potable water installations
 Domestic heating circuits and radiator connections
 General plumbing repairs and retrofits where a reducer is needed
Key specifications
 Material: engineered plastic for plumbing use
 Connection sizes: one end 25 mm, other end 16 mm
 Color: gray
 Function: reducer coupling for pipe diameter transition

How to use
Ensure both pipe ends are clean, cut square and free of burrs before assembly. Slide the corresponding 25 mm and 16 mm pipes into each end of the coupling until fully seated according to the pipe manufacturer's insertion depth guidance. Confirm that seals or O-rings (if present) are intact and positioned correctly. After connection, test the system at working pressure to verify there are no leaks and that flow is as expected.
Usage recommendations
Use appropriate pipe preparation tools and follow local plumbing codes. For long-term reliability, avoid exposing the plastic coupling to direct UV radiation or aggressive chemicals, and perform pressure testing after installation to confirm a secure joint.
