## Long description

The VIEGA Sleeve Coupling Mufa 18x1/2 GW Profipress S is a press-fit adapter that connects 18 mm copper or Profipress S compatible tubing to a 1/2" female threaded outlet. Designed for plumbing and heating systems, the coupling creates a reliable mechanical press connection without soldering. Its compact form factor supports installations where a threaded connection is required for valves, fittings or service points while maintaining the press-fit advantages of speed and leak-resistant joints.
Advantages
The coupling enables fast, solder-free joining of 18 mm pipe to a 1/2" female thread using Profipress S press technology. It provides a secure mechanical connection suitable for potable water and central heating systems, reducing installation time and the need for open flame. The compact design allows installation in confined spaces and supports downstream threaded components such as valves and meters.
Suitable for
Domestic potable water supply lines with 18 mm copper or compatible pipes
Heating circuits and radiator connections requiring a 1/2" threaded outlet
Service connections, shut-off valves and flow measurement installations
Retrofit or new-build plumbing where press-fit to threaded transitions are needed
Key specifications
Connection A: press-fit for 18 mm copper or compatible Profipress S tubing
Connection B: 1/2" female thread for standard threaded fittings
Material: corrosion-resistant metal suitable for potable water and heating systems
Suitable working media: potable water and heating fluids as per system guidelines
Installation method: mechanical press connection using Profipress S tooling
How to use
Prepare the 18 mm pipe by cutting squarely and deburring the end. Insert the pipe fully into the press-fit end of the coupling and position the press tool over the designated press zone. Complete the press operation in accordance with Profipress S tool and ring specifications. After pressing, attach the required 1/2" threaded fitting or valve to the female thread and tighten to the manufacturer's recommended torque. Verify the joint and threaded connection for tightness and perform system pressure testing per applicable installation standards.
Usage recommendations
Use certified Profipress S pressing tools and jaws appropriate for 18 mm fittings. Confirm material compatibility with system media and follow local plumbing codes for potable water or heating installations. Where accessible, leave adequate space for wrenching the 1/2" threaded component and for future maintenance or replacement.
