## Summary description

VIEGA pipe coupling for connecting 16 mm pipe to 3/4 in threaded fittings. Made of brass with a polished finish, this connector provides a durable mechanical join between metric pipe and imperial threaded components.

## Long description

VIEGA pipe coupling 16 x 3/4 in, brass, polished is a mechanical connector designed to join 16 mm plastic or metal tubing to 3/4 inch threaded fittings. Manufactured from brass with a polished surface, the coupling provides a corrosion-resistant interface that facilitates a secure transition between metric pipe dimensions and imperial threaded components in plumbing and heating systems.
Advantages
The brass construction ensures good mechanical strength and resistance to corrosion while the polished finish reduces surface oxidation and simplifies cleaning. The coupling offers a reliable, durable connection without the need for soldering, enabling fast installation and maintenance. Its design minimizes the risk of leaks when correctly installed and is compatible with common plumbing and heating materials.
Suitable for
 Connecting 16 mm pipe to 3/4 in threaded valves and fittings
 Domestic water supply systems
 Heating circuit connections and radiator feed lines
 Plumbing repairs and retrofits where metric-to-imperial transition is required
Key specifications
 Connection types: 16 mm pipe end to 3/4 inch male/female threaded end
 Material: brass
 Finish: polished
 Application: potable water and heating systems (mechanical coupling)
 Installation method: mechanical joint without soldering
How to use
Prepare the 16 mm pipe by cutting it square and deburring the end. Ensure the threaded fitting is clean and in good condition. Slide the coupling onto the 16 mm pipe and engage the threaded end with the mating fitting; tighten according to recommended torque for the fitting materials to ensure a leak-free joint. If the coupling includes sealing elements, verify they are correctly positioned. After assembly, pressurize the system and inspect for leaks before putting the installation into regular service.
Usage recommendations
Use appropriate sealing tape or approved sealants on the 3/4 in thread where required by system specifications. Avoid over-tightening to prevent damage to threads or deformation of the coupling. Select materials and installation practices in accordance with local plumbing codes and the intended fluid (potable water or heating medium).
