Viega press connectors are equipped with the SC-Contur. The SC-
Contur is a safety technology that is certified by the DVGW and ensures
that the connection is guaranteed to leak in an unpressed state. In this
way, unpressed connections are noticed immediately during a leakage
test.
Viega guarantees that unpressed connections are visible during a
leakage test:
n
with wet leakage test in the pressure range from 0.1 hPa–0.65 MPa
(1.0 mbar–6.5 bar)
n
with dry leakage test in the pressure range from 22 hPa–0.3 MPa
(22 mbar–3.0 bar)

Markings on components
The press connections are marked with a coloured dot. This identifies
the SC-Contur, where the test medium would escape in the case of an
inadvertently unpressed connection.
