Profipress
General
Press connector system with press connectors made of copper and silicon bronze tested in acc. with DVGW worksheet W 534 with DVGW test seal and pipes made of copper in acc. with EN 1057 in acc. with DVGW worksheet GW 392.
Suitable for drinking water installations in acc. with DIN 1988.
For dimensionally stable concealed and pre-wall installations of manifold and riser pipes in Viega component assembly.
Press connectors
All sizes with SC‑Contur - connections, which remain unpressed become visible when the system is filled. The SC‑Contur is certified and fulfils the requirements of DVGW worksheet W 534, Point 12.14, Connectors with forced leakage.
During leakage tests with water, Viega guarantees the identification of unpressed connections in the pressure range 0.1 MPa–0.65 MPa, in the case of a dry leakage test with compressed air or noble gases from 22 hPa–0.3 MPa.

Note– Limitations of use drinking water
Pipes and connectors made of copper may only be used when the pH value of the drinking water is pH ≥ 7.4 or the total volume of organic carbon does not exceed TOCmax = 1.5 mg/l at values between pH = 7.0‑7.4!
Note Limitations of use heating systems
Observe VDI 2035 and EN 12828!

Use of press tools
The functional safety of the Viega press connector systems is primarily dependent on the perfect condition of the press tools and press machines used. For this reason, for the production of press connections, we recommend the use of Viega press tools and their regular inspection by authorised service points.
Technical data
Press connectors and components are constantly being optimised. If required, the current Z and installation dimensions can be obtained from the download area of the Viega website: www.viega.co.uk
