## Summary description

Transitional pipe fitting VIEGA GZ 20 x 1/2 in polished brass. Designed to connect a 20 mm pipe to a 1/2" threaded female/male connection (GZ), providing a durable brass interface for plumbing systems.

## Long description

Transitional pipe fitting VIEGA GZ 20 x 1/2 in polished brass is designed to connect a 20 mm smooth pipe to a 1/2" threaded connection (GZ) in plumbing and heating systems. The fitting provides a solid brass interface that ensures mechanical stability and reliable sealing when joining pipework to threaded valves, fixtures or adapters. Its polished surface offers improved corrosion resistance and facilitates cleaning during installation and maintenance.
Advantages
The brass construction delivers good mechanical strength and long-term resistance to corrosion in typical potable water and heating environments. The polished finish reduces surface oxidation and eases handling during assembly. The transitional geometry enables a straightforward connection between a 20 mm pipe and a standard 1/2" threaded component without the need for additional adapters, simplifying installation and reducing leak points.
Suitable for
 Connecting 20 mm copper, brass or compatible plastic pipes to 1/2" threaded valves and fixtures
 Domestic water supply installations
 Heating system connections where a pipe-to-thread transition is required
 Repair or replacement of threaded plumbing components
Key specifications
 Material: brass, polished surface
 Connection A: 20 mm smooth pipe connection
 Connection B: 1/2" G (threaded) connection
 Application: water supply and heating systems
 Corrosion resistance: polished finish for improved surface protection
How to use
Prepare the 20 mm pipe by deburring and ensuring a clean, square cut. Slide the pipe into the fitting's 20 mm end and secure according to the system type (e.g., soldering, press-fit or compression method as appropriate for the specific pipe material and the fitting version). Thread the 1/2" G connection to the mating threaded component using appropriate sealing method (PTFE tape or sealing compound) if required for the assembly. Tighten to the recommended torque for the mating component to avoid thread damage and ensure leak-free connection.
Usage recommendations
Verify compatibility of the fitting with the pipe material and the joining method used (solder, press, compression). Use suitable thread sealant on the 1/2" connection when connecting to threaded valves or fittings designed for tape or compound. Inspect threaded joints and the polished surface during periodic maintenance to detect any signs of wear or leakage.
