Viega Press Technology Water System
PRESS TECHNOLOGY WATER SYSTEM
PRESS TECHNOLOGY WATER SYSTEM
More than 15 years ago, Viega set a milestone in installation technology with Profipress: the copper piping system was the first to be pressed – not soldered – as standard.
The use of press connectors with other materials such as stainless steel or plastic piping systems for water, heating, gas or compressed air has become “state of the art” in many countries
Traditionally, copper pipes for building services were hard or soft soldered, depending on the application and medium. However, the press connecting technology developed by Viega through to system maturity some 20 years ago offers a more practical alternative.

VIEGA INTEGRATED SYSTEM
The versatile requirements of practical life demand complex solutions. As a leading manufacturer in building services engineering, Viega considers this in the system and makes it possible to combine a huge range of materials with one another
FLEXIBLE AND STABLE
The Pexfit Pro concealed connection socket is a Viega solution especially for pipe-in-pipe installations. It protects the interface to the water fitting against building site conditions and allows a simple pipe exchange without any damage to tiles.
THE VIEGA SC-CONTUR
Even at very low flowing pressure, water will leak out of the SC-Contur of a connector, which has not been pressed properly. This prevents expensive subsequent damage. Press connectors are both quicker and safer: processing requires less time, and the SC-Contur from Viega shows up any forgotten pressings at the first filling of the unit or during a leakage test, for example, with water.
QUALITY MADE IN GERMANY
Irrespective of whether it is copper, stainless steel, gunmetal or plastic – Viega press technology connects a huge range of materials safely with one another, meaning it always contributes to an economical overall solution. Planned to precision, perfectly thought-out and completely from a single source.

A SINGLE COMPACT PRESS TOOL
The pressing operations are executed with the matching press tools and jaws. As well as mains powered press tools, there are also battery powered tools which provide a high degree of flexibility. Their extremely compact design means they can also be used to work in difficult-to-access locations, such as in installation ducts. 180° swivelling jointed press jaw sets provide even greater flexibility where required.
VIEGA PRESSGUN
No oxygen or gas cylinder, no burner, no soldering accessories – instead, just one of the three comfortable Viega Pressguns. Viega press technology works with a unique press tool.
UP TO 50 PERCENT FASTER PROCESSING RATE AND GUARANTEED SAFETY
In many countries in Europe these piping systems are even approved for gas installations! The key pillar supporting this safety guarantee is the SC-Contur, which only Viega press connectors provide. Even before pressing begins, water quite visibly emerges on charging the system with a pressure of 1.0 to 6.5 bar. In "dry" leakage testing, the pressure across the entire pressure range immediately drops from 3.0 bar to 22.0 mbar – meaning the unpressed connection can always be reworked in order to prevent damage in system operation.
A CLEAR ADVANTAGE IN TERMS OF SAFETY
Due to tight production tolerances, the pipe and connector appear to be “sealed” even before they have been pressed. Connections can be loosened by pressure surges whilst the unit is in operation; uncontrolled water can quickly cause a considerable amount of damage. Even at very low flowing pressure, water will leak out of the SC-Contur of a connector, which has not been pressed properly. This prevents expensive subsequent damage.
FIRE HAZARD ELIMINATED
There is another reason why press connecting technology has had such success internationally: its enhanced processing safety, particularly compared to soldering. As pressing involves no open flame, and so poses no fire hazard, no fire safety measures are needed. Consequently, press-connected pipes can often even be installed in explosive industrial environments without interrupting production operations.
Such applications also benefit from the breadth of the Viega range which, alongside the Profipress and Profipress G copper systems, also includes coordinated piping systems in stainless steel (Sanpress and Sanpress Inox) and galvanized steel (Prestabo) as well as dimensionally stable piping (Pexfit Pro).
This means piping installations for a wide variety of media can be executed by a single contractor, using one press tool and the press jaws.
PRESS CONNECTORS FOR ALL JOBS
The core of the system is the world-recognised Viega press technology with SC-Contur. It guarantees security and flexibility. This is because the Viega press connector range includes versatile installation and connection designs, even in large dimensions. It offers an extraordinary scope of practical solutions with a huge versatility of different press connectors: bends, angles, crossover bends, T-pieces, threaded adaptors, sleeves, screws and fittings with press connections are available.
SIMPLER REPAIRS
The practical processing advantages of press connection technology are equally important, both in new installations as well as in any repair work being carried out on existing systems. Depending on the nominal width, a press connection is completed up to 40% faster than a soldered connection.
Another reason is that in addition to the faster pressing process, press connection technology does not have all the time-consuming peripheral jobs such as deburring and calibrating. When repairing drinking water systems, systems do not need to be fully drained beforehand.
Whereas residue dampness makes soldering or nearly welding impossible, pressing is possible even when there is still residual water in the system.
INSTALLATION TECHNOLOGY THAT CONNECTS EVERYTHING
With Viega, all opportunities are available to the specialist fitters. All components from the domestic installation can be connected to one another without any problems. For example, metallic pipework in the cellar or rising mains can be directly connected to the plastic pipework systems on the house level. The advantages of clean, stable metallic installation can then be connected perfectly with the flexibility and ease-of-installation of plastic installations.
FOR COPPER, STEEL AND STABLE COMPOSITE PIPES
Viega offers the quick and safe press connection technology for all piping systems in all common areas of use. Metallic piping systems like Profipress (copper), Sanpress (stainless steel) or Prestabo (galvanised steel pipe) are all included as is Pexfit Pro as a dimensionally stable composite pipe.
Depending on the material and area of use (e.g. drinking water, heating, gas, compressed air, fire extinguisher pipes), Viega offers suitable press connectors with the corresponding sealing elements. To prevent confusion of these press connectors, they have all been marked with coloured dots. For example, green points are exclusively for drinking water, yellow for gas installations and red for heating installations.
