Pexfit Pro

Press connector systems for potable water installations in acc. with DIN 1988 and DIN 50930‑6 as well as heating installations, tested in acc. with DVGW worksheet W 534.

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 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 of 0.1 MPa–0.65 MPa, in the case of a dry leakage test with 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.
