## Long description

VIEGA transition fitting 16 x 1/2 in copper, polished is a metal connection component designed to join a 16 mm copper pipe to a 1/2-inch threaded outlet.

 Material: copper with polished finish
 Connection type: transition between 16 mm tube and 1/2-inch threaded connection
 Application: water supply and heating systems

How to use
Prepare the 16 mm copper pipe by cutting squarely and deburring the end. Ensure the mating threaded connection is clean and free of old sealant. Insert the copper tube into the fitting according to the installation practice appropriate for the chosen joining method (soldering, press or compression as applicable for the specific system) and tighten the 1/2-inch threaded side to the receiving thread using appropriate tools. Follow applicable plumbing codes and use approved sealing materials on the threaded joint if required.
Usage recommendations
Use the fitting only within the temperature and pressure limits of the installed plumbing system. For soldering or brazing, protect nearby components and follow safety procedures. Verify compatibility with system fluids and check all joints for leaks after installation.
