VIEGA transition fitting 16 x 1/2 in copper, polished (MPN 729530)

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. Manufactured to fit common plumbing dimensions, this polished copper fitting provides a corrosion-resistant metal-to-thread interface for water supply and heating systems. The component is intended for installations where a change of pipe dimension or a threaded connection is required and is suitable for both new installations and repair work.

Advantages

The polished copper construction ensures good conductivity and resistance to corrosion while offering a smooth surface finish that simplifies inspection and cleaning. The transition design allows secure joining between a 16 mm copper tube and a 1/2-inch threaded connection without the need for complex adaptors. Compatibility with standard plumbing thread sizes and a compact form factor make the fitting easy to integrate into tight spaces and existing pipework.

Suitable for

• Residential potable water supply lines
• Heating circuits and radiator connections
• Repair and retrofit work where a copper tube must connect to a 1/2-inch threaded fitting
• Plumbing installations requiring a metal-to-thread transition

Key specifications

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

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.
