Ä „Regulations from section: Pipes“ on page 7
2.3.3 Press connectors
Fig. 1: Repair coupling
The connector has a support body with a sealing contour on it. A
sealing element is no longer required due to the sealing contour. During
pressing, the pipe is pressed onto the sealing contour and sealed from
the inside, attaching the connector permanently to the pipe. On the
repair side, the repair coupling has an end-to-end support body. It is
equipped with a specifically shaped clamping ring to allow it to be
pushed onto the pipe. The connector has a window for checking the
insertion depth.
Product information
Geopress K repair coupling 10 from 23

Fig. 2: 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.
Viega guarantees that unpressed connections are visible during a
leakage test.

2.3.4 Markings on components
Fig. 3: Marking
The yellow-green dot shows that the press connector is equipped with
the SC-Contur and that the connector is suitable for drinking water and
gas.
The position of newly laid pipes and connection lines, including detailed
information about pipeline parts, must be documented and regularly
updated. The traceability code on the connector allows every connector
to be traced back and simplifies the documentation in as-completed
drawings.

tions from section: Notes on mounting“ on page 8.
nDents
nCracks
nGrooves (maximum depth 10 % of nominal wall thickness)
ndamaged pipe ends
Only process the sections of the pipes, which do not exhibit these fea‐
tures.

NOTICE!
Leaky press connections due to pipes being too short!
If two press connectors are to be mounted onto a pipe
without an interval, the pipe must not be too short. If the
pipe is not inserted up to the prescribed insertion depth in
the press connector during pressing, the connection may
become leaky.
