General

Profipress G

copper/gunmetal

Press connector system with press connectors and pipes made of copper in acc. with DIN EN 1057 and DVGW worksheet GW 392 suitable for:
  • Gases in acc. with DVGW G 260 in gas installations in acc. with DVGW-​TRGI 2008 (DVGW worksheet G 600) / DVFG-​TRF 2012
  • Liquid gas in the gas phase for domestic and commercial applications, tested in acc. with DVGW worksheet G 5614
  • Heating oil pipelines for heating oil in acc. with DIN 51603‑1
  • Diesel fuel pipelines for diesel fuel; as suction and pressure pipelines in acc. with DIN EN 590 in consideration of the general technical approval Z-38.4‑71

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 G 5614, point 4.4.1, 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.

Marking
Yellow dot, yellow rectangle and inscription »Gas MOP 5 / GT1«

Sealing elements

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: viega.com
