Fig. 4: SC-Contur
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 connector is guaranteed to be leaky in an unpressed state. In
this way, inadvertently unpressed connections are noticed immediately
when filling the system.
Viega ensures that inadvertently unpressed connections during installa‐
tion become visible when the system is filled.

Markings on components
The pipe markings contain important information regarding the quality
and certification of the pipes. Their meaning is as follows:
n
manufacturer
n
System name
n
pipe material
n
size / wall thickness
n
certification and operating temperatures
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.
