## Summary description

Copper reducing coupling SANHA model 5240 (28 x 22 mm) for joining pipes of different diameters. Constructed from copper, this threaded or solder-compatible fitting provides a transition between 28 mm and 22 mm pipe sizes. Suitable for plumbing, heating and potable water systems where a durable, metal reduction coupling is required.

## Long description

Copper reducing coupling SANHA 28 x 22 mm model 5240 is a metal pipe fitting designed to join two copper pipes of different diameters. Manufactured from copper, the coupling provides a reliable transition between 28 mm and 22 mm pipe sizes and is compatible with soldering and threaded connections where appropriate. It is intended for installations that require a compact, corrosion-resistant reducer within plumbing, heating and potable water systems.
Advantages
The copper construction ensures good thermal and electrical conductivity and long-term resistance to corrosion in common domestic and commercial water systems. The reducing coupling is compact and provides a clean mechanical join between 28 mm and 22 mm pipes with stable alignment. Compatibility with soldering and threaded assemblies allows flexible installation methods depending on site requirements and installer preference.
Suitable for
 Domestic and commercial potable water supply lines
 Central heating and radiator connections
 Plumbing repairs and retrofits where diameter reduction is needed
 Systems requiring metal fittings with solder or thread-compatible joints
Key specifications
 Material: copper
 Connection sizes: reduction from 28 mm to 22 mm
 Compatible connection methods: soldering and threaded assemblies (where applicable)
 Typical application: potable water, heating and general plumbing
 Design: compact reducing coupling for inline pipe transition
How to use
Select the coupling that matches the pipe outer diameters (28 mm and 22 mm). Prepare pipe ends by cutting square, deburring and cleaning surfaces to remove oxides and contaminants. For soldered joints, apply appropriate flux and heat uniformly until the solder flows to form a capillary bond. For threaded assemblies, ensure compatible threads and use suitable sealing method such as PTFE tape or appropriate joint compound. After assembly, inspect the connection and perform pressure testing according to local codes and standards before putting the system into regular service.
Usage recommendations
Use the coupling only with compatible copper pipe sizes and follow relevant plumbing standards. Ensure proper preparation of pipe ends and select the correct joining method (soldering or threaded) for the installation environment. Perform pressure and leak tests after installation and avoid exposure to dissimilar metals without suitable isolation to prevent galvanic corrosion.
