## Long description

VIEGA copper coupler 28 mm two-way (double pass) model 100698 is a copper plumbing fitting designed to join and extend 28 mm copper pipes in potable water and heating systems. The fitting delivers a continuous copper connection that maintains compatibility with standard 28 mm pipe dimensions and supports common plumbing installation practices. Its construction provides mechanical strength and corrosion resistance typical of copper fittings used in domestic and commercial installations.
Advantages
The coupler offers a compact, symmetrical design that enables straightforward inline joining of two 28 mm copper pipes.

Key specifications
Material: copper
Nominal diameter: 28 mm
Configuration: two-way (double pass) inline coupler
Compatibility: designed for standard 28 mm copper pipes used in water and heating systems

How to use
Prepare the pipe ends by cutting square and removing burrs, then clean and, if required by the joining method, apply flux. Insert each 28 mm copper pipe fully into the coupler until it reaches the internal stop. Join by the appropriate method for copper fittings—soldering (capillary brazing) or approved mechanical joining procedure—following applicable national standards and the installer’s guidelines. After joining, inspect the joint and perform a pressure or leak test as part of the commissioning process.
Usage recommendations
Use compatible tools and materials for copper connections and observe local plumbing codes. When soldering, ensure correct temperature control and ventilation. For potable water systems follow any water safety and installation standards relevant to your region.
