## Long description

VIEGA copper bypass coupling 18 mm model 104672 is a copper plumbing fitting designed to join or bypass sections of 18 mm copper pipe. Manufactured from copper, the coupling provides a durable, corrosion-resistant mechanical connection suitable for potable water and heating systems. It is intended for repair, modification or extension of existing installations in residential and commercial buildings where a direct copper-to-copper bypass is required.
Advantages
The copper construction offers natural corrosion resistance and thermal stability, supporting long service life in potable water and heating applications. Its compact 18 mm diameter makes it compatible with standard 18 mm copper tubing and allows straightforward integration into tight spaces. The coupling provides a reliable mechanical joint that facilitates rapid repair or rerouting without the need for complex adapters.
Suitable for
Repairing leaks or damaged sections in 18 mm copper water supply lines
Bypassing valves or fittings during maintenance or replacements
Extending existing 18 mm copper potable water or heating circuits
Temporary or permanent rerouting of 18 mm copper pipework in residential and commercial buildings
Key specifications
Material: Copper
Nominal pipe size: 18 mm
Application: Potable water and heating systems
Connection type: Mechanical copper coupling for copper tubing
Typical installation environment: Indoor plumbing and heating installations
How to use
Ensure the system is depressurized and drained before installing the coupling. Prepare the 18 mm copper pipe ends by cutting squarely and deburring to ensure full insertion. Slide the coupling onto one pipe end, align the opposite pipe, and push both pipe ends fully into the coupling until seated. Depending on your local plumbing practice and building codes, secure the joint by brazing, soldering, or using the specified mechanical joining method for the coupling. Verify alignment and test the system for leaks after re-pressurizing.
Usage recommendations
Inspect pipe ends for corrosion or damage before installation and replace any compromised sections. Follow local plumbing codes and manufacturer guidance regarding allowable joining methods and any required flux or filler materials when soldering or brazing copper. Use appropriate personal protective equipment and ensure connections are tested under normal operating pressure before returning the installation to service.
