## Summary description

VIEGA pipe reducer fitting 25 x 1 mm in copper with a polished finish. Designed as a transition connector for plumbing applications to join pipes with a 25 mm outer diameter to a 1 mm (thread/liner) interface. Suitable for domestic and commercial water installations where a compact reducer is required for reliable mechanical connection and corrosion resistance.

## Long description

VIEGA pipe reducer fitting 25 x 1 mm in copper with a polished finish is a transition connector designed for plumbing systems where a compact reduction from a 25 mm outer diameter pipe to a 1 mm threaded or liner interface is required. The fitting provides a mechanical connection between dissimilar pipe sizes while taking advantage of copper's natural corrosion resistance and thermal conductivity. Its polished surface facilitates installation in visible or confined spaces and supports long-term service in domestic and commercial water installations.
Advantages
The copper construction ensures reliable corrosion resistance and durability in potable water and heating systems. The polished finish gives a smooth surface that is easy to clean and inspect. The compact reducer design minimizes space requirements and simplifies integration into existing pipe runs. The fitting provides a secure mechanical transition that reduces the need for additional adapters or complex assemblies.
Suitable for
Joining a 25 mm outer diameter copper pipe to a 1 mm threaded or liner connection
Residential potable water supply lines
Commercial water installations and service risers
Situations requiring a compact, polished transition fitting in confined spaces
Key specifications
Material: copper
Finish: polished
Input pipe diameter: 25 mm outer diameter
Output connection: 1 mm threaded/liner interface
Application: mechanical transition reducer for plumbing systems
How to use
Prepare the 25 mm copper pipe by cutting squarely and deburring the end. Ensure the mating 1 mm threaded or liner connection is clean and properly aligned. Slide the reducer onto the 25 mm pipe and secure the threaded/liner interface according to the installation practice for the receiving component, ensuring a tight mechanical fit. Verify alignment and test the joint for leaks under normal system pressure before completing insulation or concealment. Follow local plumbing codes and standard installation procedures for copper fittings.
Usage recommendations
Use appropriate tools for cutting and deburring copper pipe to avoid damage to the reducer fitting. Avoid overtightening threaded connections to prevent deformation. For potable water applications, install accessible isolation valves and perform pressure testing after assembly. When used in heating systems, allow for thermal expansion and follow manufacturer guidance for compatible sealants or joint compounds.
