Profipress S


Profipress S

Press connector system with press connectors made of copper, gunmetal or silicon bronze* tested in acc. with DVGW W 534 with DVGW test seal, pipes made of copper in acc. with DIN EN 1057, for heating systems with operating temperatures of T = 140 °C and short-​term peak temperatures of Tmax = 280 °C, e.g. solar, district heating and low pressure steam systems.

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.

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

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 homepage:

*) Change of material due to current swith of production from gunmetal to the worldwide available alloy silicon bronze
