## Long description

TECE solder connection coupling 16×18 mm model 713916 is a plumbing fitting intended for creating a permanent metal joint between copper or compatible pipes of differing diameters. Designed for soldering, the coupling provides a sealed, mechanically stable connection suitable for potable water and heating systems where a reliable, long-lasting joint is required. The 16×18 mm dimension allows transition between common pipe sizes used in residential and commercial installations.
Advantages
The coupling is made for soldered joints, offering a continuous metal-to-metal connection that provides strong mechanical stability and corrosion resistance when installed correctly. Its stepped 16×18 mm design enables a direct transition between two pipe diameters without additional adapters. The product is compatible with standard soldering techniques and materials used in plumbing, allowing for secure, leak-resistant joints in permanent installations.
Suitable for
 Connecting copper or similarly compatible pipes of 16 mm to 18 mm diameters
 Water supply systems in residential and commercial buildings
 Heating circuits and radiator connections that require soldered joints
 Professional plumbing repairs and new installations
Key specifications
 Connection method: solder (sweat) joint
 Material: metal suitable for soldering with copper pipes
 Size: stepped 16 mm to 18 mm
 Application: potable water and heating installations
 Joint type: permanent, sealed metal connection
How to use
Prepare pipe ends by cleaning and deburring, and ensure both pipe and coupling surfaces are free from oxidation and contaminants. Apply suitable flux to the joint area, insert the pipe ends into the corresponding coupling sockets, and heat the joint evenly with a propane or MAPP gas torch until solder flows and fills the joint. Allow the assembly to cool naturally before handling and test the connection for leaks according to applicable standards.
Usage recommendations
Use certified solder and flux compatible with potable water systems where required. Follow local plumbing codes and safety practices when performing soldering work, including adequate ventilation and protection against burns. For installations involving different pipe materials, verify compatibility before soldering.
