Profipress S


Profipress S

Press connector system with press connectors made of copper, gunmetal or silicon bronze*, tested according to DVGW worksheet534 with DVGW test seal, pipes made of copper according to DIN EN 1057, for heating installations with operating temperatures of T = 140 °C and short-​term peak temperatures of Tmax = 280 °C, e.g. solar, district heating supply and low-​pressure steam systems.

Press connectors
All sizes with SC‑Contur – accidently unpressed connections become visible during filling the system. The SC‑Contur is certified and fulfils the requirements of the DVGW worksheet534, 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 dry leakage tests with compressed air or noble gases from 22 hPa–0.3 MPa.

The use of Profipress S and Profipress connectors with FKM sealing elements in potable water and gas installations is not permitted!

Use of press tools
The functional safety of the Viega press connector systems primarily depends 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 homepage:

*) Change of material due to the current switch of production from gunmetal to the Viega worldwide uniform silicon bronze alloy
