## Long description

VIEGA copper bypass connector 18 mm 1K (model 104481) is a single-piece copper fitting designed for joining or bypassing sections of 18 mm copper pipe in plumbing and heating systems. The connector provides a metallic, solderable connection that integrates with standard copper piping to maintain fluid transport continuity during repairs, line rerouting, or system modifications in residential and commercial installations.
Advantages
The single-piece copper construction offers mechanical strength and thermal compatibility with copper piping, reducing the risk of galvanic corrosion at the joint. Its 18 mm diameter matches common copper tube dimensions, enabling straightforward installation with conventional soldering or brazing methods. The metallic design provides long-term resistance to pressure and temperature cycles typical for potable water and heating circuits.
Suitable for
 Repairing damaged sections of 18 mm copper piping
 Bypassing valves or components during maintenance
 Rerouting short pipe runs in domestic heating systems
 Integrating into commercial copper pipe networks where a metallic bypass is required
Key specifications
 Material: copper
 Connection type: single-piece bypass connector suitable for soldering/brazing
 Applicable pipe diameter: 18 mm
 Design: one-piece construction for a continuous metallic joint
 Typical application: plumbing and heating system fluid transport
How to use
Prepare both pipe ends by cutting squarely and cleaning to bare copper. Position the VIEGA copper bypass connector on the prepared pipe ends, ensuring proper alignment and insertion depth. Apply appropriate flux and perform soldering or brazing according to local codes and the solder material specifications used in the installation. Allow joints to cool and inspect visually for complete solder coverage and absence of gaps before pressure testing the system.
Usage recommendations
Use compatible solder and flux rated for potable water if the system carries drinking water. Observe local plumbing codes and safety procedures during heating and soldering operations, including adequate ventilation and use of heat shields when near combustible materials.
