Viega Propress: the complete system for copper piping installations
Viega was the first to offer press joining systems in Australia, the first to offer a proven method to verify secure connections and the first to offer the same time-saving press technology in multiple materials. Viega Propress systems also offer Viega Smart Connect technology, which helps installers easily identify unpressed connections.

Best drinking water quality
Cold or hot water – Viega Propress offers the right components for every drinking water installation – of course, with certified quality.
Certified quality
Thanks to high quality materials and components, Viega Propress provides drinking water installations that are corrosion-resistant and sealed over the longer term. The system has WaterMark certification in accordance to AS 3688 standard, license No. LN21120. This requires testing to AS/NZS4020, which guarantees peace of mind when used for the drinking water installations. Viega Propress is therefore approved for the Australian market with dimensions DN 15 to DN 100 for connection of AS 1432 copper tube; types A, B and C.
Unmistakeable Propress
Viega Propress products for drinking water installations are easy to identify from the green dot on the bead and are fitted with a black EPDM sealing element. The high-quality sealing element is designed to withstand temperatures of –20 degrees Celsius to 110 degrees Celsius and is pressure-resistant up to 1600 kPa.
Maximum safety
Safety is a top priority for gas installations. Propress G ensures that installation specialists already work to the right safety standards throughout the installation procedure. Thanks to Viega, using the press technology ensures complete installations can be finished amazingly fast, efficiently and, most importantly, with no fire hazards. Brazing is yesterday’s technology!
Virtually manipulation proof
Once Viega Propress fittings have been pressed, they can no longer be separated. This makes the press connections virtually impossible to manipulate or interfere with. Another safety bonus: thanks to the Viega Smart Connect-Feature, is that unpressed Propress G fittings are visibly leaky during a leakage test.
Mistakes are out of the question
The yellow dot on the bead, a yellow rectangle with the word “GAS” as well as yellow HNBR sealing element make the Viega Propress G visually distinctive and clearly identifiable. The yellow packaging is also easily distinguished at a glance from the Viega Propress components for drinking water installation.
Quality assured reliability
Viega Propress G has a yellow HNBR sealing element designed to withstand temperatures from –40 to 70 degrees Celsius as well as a maximum pressure of 500 kPa. The system is approved for the entire Australian market – in dimen-sions DN 15 to DN 100 for connection of AS 1432 copper tube; types A and B.
Smart Connect-Feature
All Viega press fittings offer a unique safety factor: the Viega Smart Connect-Feature. Thanks to this technology, which has been tried and tested a million times, unpressed fittings are guaranteed to leak during the pressure test.
We guarantee:
Unpressed fittings are visibly permeable Viega press fittings with Smart Connect-Feature work with both compressed air and water. If the connection has a leak, the “dry” leakage test will show a visible pressure decrease over the entire pressure range from 2,2 kPa to 300 kPa. If the leakage test is carried out with water, this visibly escapes from the unpressed fittings in the pressure range of 100 kPa to 650 kPa. Another advantage of the Viega press connection is the cylindrical pipe insertion. This prevents damage to the sealing element during the assembly process.
Special features of the Propress system
High level of safety thanks to the Viega SC-Contur
The Viega SC-Contur feature on each press connector means that any inadvertently unpressed connection points will visibly leak when the system is filled. It also allows the entire system to be monitored with a centralised leakage test. This eliminates the need for time-consuming visual checks while also reducing the amount of work required and the risk of leaking connections.
The highest standards of drinking water quality
When it comes to drinking water installations, Viega Propress sets new standards in quality and hygiene. Because of the high-quality materials used – namely copper or silicon bronze – hygienic drinking water is guaranteed at every draw-off point with absolutely no risk of an unacceptable change in drinking water quality. The hygienic packaging of the Propress connectors keeps them in optimum condition from production through to assembly for the best possible drinking water quality.
Impressive solutions for industrial applications
The Propress G product range is perfectly tailored to the different requirements of technical gases, lidquid gases, compressed air and oils.
The high-quality elastomer sealing elements are precisely matched to the respective media. HNBR sealing elements are ideal for gas installations. The durability and strength of the sealing element are specially tailored to the medium of gas. With Propress G, users are always on the safe side.
Flexibility for all dimensions
Viega Propress offers the highest degree of flexbility for gas and drinking water installations. This is guaranteed with multiple components that are suitable for dimensions from DN 15 to DN 100.
A proven concept: ring system or series pipeline
Continuous water exchange is important for maintaining drinking water quality. For this reason, any draw-off points that are not used regularly should be installed in a ring or as a series pipeline. Viega offers the right technology for both scenarios.
Hygiene and safety on the construction site
The hygienic packaging of the Viega Propress connectors keeps them in optimum condition from production through to assembly for the best possible drinking water quality. In addition, the QR code provides quick information about the products. Doing away with the plugs for the connectors means there is no additional environmental impact.
The Propress assembly process – quick, clean and safe
Advantages of press connection technology at a glance
Time savings
Using the pressing technique to connect piping reduces installation time significantly. Much less effort is required compared to conventional methods such as welding or soldering and it can even be used in hard-to-reach areas. The system elements can be joined together in less than 20 seconds, reducing assembly time by up to 80 %.
Reliability
With our stringent quality standards, high-quality materials and continuous innovations, we ensure reliable press connections. The Viega SC-Contur feature makes any inadvertently unpressed connections clearly visible. It is included in all press connectors and enables a centralised leakage test to be performed.
Cost efficiency
The perfect symbiosis of quality and economic efficiency. Viega press connection technology is the effective way to save time and money. Not only does it eliminate the special steps associated with processes such as welding or soldering, but the pressing method also makes the system less prone to faults and therefore more durable than the alternatives.
Safety
No flames or fumes are generated when pressing pipe connections and the process is absolutely fireproof. This reduces the risks posed by flying sparks or human error – a major advantage, especially in sensitive or hard-to-reach environments. It also minimises the need for special health and safety measures and permits.
