General

Megapress G

Press connector system with press connectors made of non-​alloy steel 1.0308 for black, galvanised, industrially painted and powder-​coated steel pipes in acc. with EN 10255 and in acc. with EN 10220 / EN 10216‑1 as well as EN 10220 / EN 10217‑1, gases in acc. with DVGW worksheet G 260 in gas installations in acc. with DVGW-​TRGI 2008 (DVGW worksheet G600) / DVFG-​TRF 2012.
  • Natural gas/Liquid gas in the gas phase for domestic and commercial applications, tested in acc. with DVGW worksheet G 5614-B1

Press connectors
Megapress G press connectors are made of non-​alloy steel 1.0308 with an external galvanic zinc-​nickel coating.
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-B1, Point 4.4.1, Connectors with forced leakage.
During leakage tests with compressed air, Viega guarantees the identification of unpressed connections in the pressure range from 22 hPa–0.3 MPa.

Protection against external corrosion
Thanks to a high-​quality zinc-​nickel coating the press connectors are optimally protected against corrosion.
The pipe being use should be protected with suitable corrosion prevention measures - observe manufacturer's information.

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
