## Long description

SANHA SANHA-Therm Mufa przejściowa ZWxGW 18x1/2 is a copper transition coupling for plumbing and heating systems that connects an 18 mm copper tube to a 1/2" female threaded fitting. The fitting enables a secure metal-to-thread transition between metric tubing and BSP/pipe thread components, intended for potable water installations, heating circuits and general sanitary use. Constructed from copper, it offers corrosion resistance and thermal conductivity suitable for hot and cold water applications.
Advantages
The copper construction provides good resistance to corrosion and thermal stress while maintaining mechanical strength for pressure-tight connections. Its design allows straightforward installation with standard soldering or brazing techniques common in plumbing and heating work. The adapter eliminates the need for intermediate fittings when joining metric tubing to threaded components, reducing potential leak points and simplifying system layouts.
Suitable for
Potable water supply lines
Heating circuits and radiators
Sanitary installations and plumbing repairs
Connections between metric copper tubing and 1/2" BSP or pipe-threaded components
Key specifications
Material: copper
Connection types: sleeve end for 18 mm tube and 1/2" female pipe thread
Intended media: hot and cold potable water, heating fluids compatible with copper
Application environment: indoor plumbing and heating systems
Joining method: soldering/brazing or appropriate copper joining technique
How to use
Prepare the 18 mm copper tube by cutting squarely and removing burrs and oxidation. Clean both the tube end and the inner sleeve of the coupling to ensure proper wetting during soldering or brazing. Assemble the tube into the sleeve and align the threaded fitting with the mating component; apply appropriate sealing material to the male thread if required by the system (e.g., PTFE tape or thread sealant compatible with potable water). Heat evenly to perform soldering or brazing following accepted plumbing practices and applicable codes, ensuring a continuous joint without gaps. After cooling, verify the threaded connection is sealed and perform a pressure test according to system requirements.
Usage recommendations
Use compatible fluxes and solders approved for potable water systems and follow local regulations for potable water and heating installations. Avoid exposure to dissimilar metals without appropriate dielectric fittings to prevent galvanic corrosion. Verify thread standards and apply correct thread sealing material for the intended working pressure and temperature range.
