Profipress G

General

Profipress G

Press connector system with press connectors made of copper, gunmetal or silicon bronze* and pipes made of copper acc. to DIN EN 1057 and DVGW worksheet GW 392 suitable for:
  • Gases in acc. with DVGW worksheet G 260 in gas installations acc. to DVGW-​TRGI 2018 (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 according to DIN EN 590 in consideration of the general building approval Z-38.4‑71

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 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 dry leakage tests with compressed air or noble gases from 22 hPa–0.3 MPa.

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: www.viega.com/downloads

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