## Summary description

SANHA-THERM C-Stahl reducing coupling (mufa) by SANHA, size d28x22. A press-fit reducing connector designed for joining pipes with different diameters (28 mm to 22 mm) in heating and plumbing systems. Constructed for use with copper and steel pipe applications where a secure, press-sealed transition is required. Suitable for domestic and commercial installations.

## Long description

The SANHA-THERM C-Stahl reducing coupling d28x22 is a press-fit connector designed to join pipes of different diameters in heating and plumbing systems. Manufactured by SANHA for mixed copper and steel pipe installations, the coupling provides a sealed mechanical connection without soldering. The compact reducing design allows a reliable transition from 28 mm to 22 mm pipework while maintaining flow and pressure characteristics required for domestic and commercial heating circuits.
Advantages
The reducing coupling offers a uniform press seal that minimizes leak risk and accelerates installation compared with traditional joining methods. Its C-Steel construction is suitable for use with steel and copper pipe materials where a robust mechanical connection is needed. The press-fit method reduces heat exposure to surrounding materials and eliminates the need for flux, open flame, or extensive drying times, supporting faster commissioning of systems.
Suitable for
Reducing a 28 mm supply or return line to a 22 mm branch in heating systems
Connections between copper and steel pipe segments in domestic plumbing
Commercial building pipe networks requiring press-fit transitions
Key specifications
Connection type: press-fit reducing coupling for mixed-material pipes
Material: C-Steel construction compatible with copper and steel piping
Size: reduces from 28 mm to 22 mm nominal diameter
Application: heating and plumbing systems (supply, return, branches)
Installation: press-connection technology for mechanical, leak-resistant joints
How to use
Select appropriate pipe ends and ensure they are cut square, deburred and clean. Position the reducing coupling on the 28 mm and 22 mm pipe ends according to the manufacturer’s marking, then use the correct press tool and jaw for C-Steel press fittings to form the mechanical seal. Verify the pressed joints for proper deformation and alignment before pressure testing the system in accordance with applicable regulations and project specifications.
Usage recommendations
Use only approved pressing tools and jaws specified for C-Steel press fittings and follow local codes for installation and pressure testing. Avoid using damaged or corroded pipe ends; replace any components that do not meet visual or dimensional standards prior to pressing.
