## Long description

SANHA transitional press coupling Purapress mufa 18 mm x 1/2" ZW x GW is a press-fit adapter designed to connect an 18 mm copper or compatible tube to a 1/2" female threaded fitting. The coupling uses Purapress press technology to create a mechanically secure and leak-resistant joint without soldering, making it suitable for potable water and heating installations where a press-to-thread transition is needed.
Advantages
The Purapress mufa provides a reliable connection that eliminates the need for flame-based joining methods, reducing installation time and safety risks. Its press technology ensures consistent compression and a durable seal suitable for water-carrying systems. The transitional design simplifies connections between press-fit tubing and standard threaded components, enabling flexible system layouts and straightforward maintenance.
Suitable for
 Domestic and commercial potable water systems
 Central heating and radiator connections
 Transitions from copper or compatible press-fit tubing to threaded valves and fittings
 Repair and retrofit work where soldering is impractical
Key specifications
 Connection A: 18 mm press-fit for copper or compatible tubing
 Connection B: 1/2" female thread (internal thread)
 Joining method: Purapress press technology (mechanical pressed joint)
 Application: potable water and heating systems
 Material characteristics: corrosion-resistant metals suitable for water installations
How to use
Prepare the tube by cutting squarely and deburring the inner and outer edges. Slide the press coupling over the prepared 18 mm tube end until it seats fully. Engage the 1/2" female-threaded component and hand-tighten to ensure proper alignment. Position the appropriate Purapress pressing tool over the press sleeve and perform the press operation according to the tool manufacturer's instructions to achieve a completed mechanical seal. Verify the pressed joint and threaded connection for correct engagement before pressure testing the system.
Usage recommendations
Use the coupling with compatible Purapress pressing tools and jaws specified for 18 mm fittings. Confirm material compatibility with the tubing and threaded components, and follow applicable plumbing standards and local regulations. Pressure-test the installation after assembly and inspect joints periodically, especially after heat cycles in heating systems.
