## Long description

SANHA 5240 copper reducing coupling 18 x 15 mm is a mechanical fitting designed to connect copper pipes of two different diameters in plumbing and heating systems. Manufactured from copper, the coupling provides a compact transition between 18 mm and 15 mm pipework and is intended for use in potable water, central heating and sanitary installations. The fitting is suitable for on-site routing, repairs and modifications where a reliable metal-to-metal connection and dimensional reduction are required.
Advantages
The coupling offers a precise, space-efficient reduction between 18 mm and 15 mm copper pipes, enabling neat pipe layouts and fewer joints. Its copper construction ensures good corrosion resistance and thermal conductivity appropriate for drinking water and heating circuits. The product is compatible with standard copper pipe dimensions and is suitable for professional plumbing work, providing a consistent mechanical connection that simplifies installation and maintenance.
Suitable for
 Reducing copper pipe runs from 18 mm to 15 mm in potable water systems
 Transitions in residential and commercial central heating circuits
 Sanitary installations such as bathroom and kitchen plumbing

Key specifications
 Material: copper
 Connection type: mechanical reducing coupling for copper pipes
 Nominal pipe sizes: 18 mm x 15 mm
 Suitable media: potable water and heating fluids
 Application areas: plumbing, central heating, sanitary installations
How to use
Prepare both pipe ends by cutting square and removing burrs and debris to ensure full contact with the fitting. Slide the coupling onto the larger diameter first if applicable, align the pipes to maintain axial continuity, then secure the joint following the chosen installation method for copper mechanical couplings (such as press-fitting, soldering or brazing) compatible with this type of fitting and with system requirements. Verify alignment and test the system for leaks after installation according to local standards and project specifications.
Usage recommendations
Use appropriate installation tools and follow applicable plumbing codes. Select the correct joining method for the coupling and system pressure and temperature conditions. When used in potable water systems, ensure cleanliness of internal surfaces before final assembly and perform a pressure test after installation.
