## Long description

The SANHA 5240 copper reducing coupling 28 x 18 mm is a soldering-type connector designed to join copper pipes of different diameters. Manufactured from copper, the coupling provides a corrosion-resistant, conductive and durable joint suitable for potable water and central heating systems. Its compact design allows installation where a reduction from 28 mm to 18 mm pipework is required, enabling secure transitions in domestic and commercial plumbing and heating networks.
Advantages
The SANHA 5240 reducing coupling offers reliable mechanical strength and consistent bore alignment for smooth fluid flow between dissimilar pipe sizes. Being fabricated from copper, it resists corrosion and supports soldered connections that form leak-tight joints when properly installed. The simple geometry and standardized dimensions facilitate compatibility with common copper tubing and soldering practices used in plumbing and heating installations.
Suitable for
Reducing a 28 mm copper line to 18 mm in potable water supply systems
Transitions in central heating circuits and radiator connections
Domestic and light commercial plumbing repairs and retrofits
Applications requiring soldered copper pipe joints with reliable corrosion resistance
Key specifications
Material: copper
Type: reducing coupling (soldering type)
Connection method: soldered joint
Nominal pipe sizes: 28 mm to 18 mm
Intended media: potable water and heating fluids
Suitable temperature range: typical for copper plumbing and heating use (consult system requirements)
How to use
Prepare the copper pipes by cutting square and deburring the ends, then clean and flux the mating surfaces according to standard soldering procedures. Slide the coupling onto the larger pipe end, position the smaller pipe into the opposite end to achieve full engagement, apply heat evenly around the joint and introduce the appropriate solder to form a continuous seal. Allow the joint to cool naturally and inspect for complete solder flow and absence of gaps before placing the system into service. Follow applicable codes and safe soldering practices throughout the installation.
Usage recommendations
Use appropriate flux and solder compatible with potable water systems, ensure proper joint cleaning and gap control, and test the system under pressure after installation. For installations involving high temperatures, aggressive fluids, or where brazing is preferred, consult relevant standards or a qualified installer to confirm suitability.
