WRAS approved, flow-optimised press connector system made of copper (99.9 % Cu-DHP), gunmetal or silicon bronze for copper pipes up to 108mm. Press connectors for protecting the sealing element equipped with cylindrical pipe guide. Press connectors from d64.0 with stainless steel cutting ring to ensure the mechanical strength of the connection.

Suitable for concealed and pre-wall installations of riser pipes and floor installation.

Sealing element:

Black EPDM (ethylene propylene diene rubber), heat-resistant up to 110°C, and not resistant against hydrocarbon solvent, chlorinated hydrocarbon solvents, turpentine or petrol. It is highly resistant to ageing, ozone, sunlight, weathering and environmental influences. The high quality EPDM sealing element is protected against damage by the internal cylindrical pipe guide.

Press connectors:

The press connectors have a circumferential bead in which the sealing element lies. The connector is deformed in front of and behind the bead, and permanently connected to the pipe during pressing. The sealing element is not deformed during pressing. Viega's distinctive hexagonal pressing pattern bonds fitting and pipe and provides the mechanical strength for the connection.

The connectors may only be pressed with Viega press machines with constant pressing force (e.g. Pressgun 6 Plus).

With SC‑Contur, any connections which remain un-pressed become visible when the system is filled. The SC‑Contur is certified and fulfils the requirements of DVGW worksheet W 534, point 12.14, connectors with forced leakage.

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

With the wet leakage test in the pressure range from 0.1–0.65 MPa (1.0–6.5 bar).
With dry leakage test in the pressure range from 22 hPa–0.3 MPa (22 mbar–3.0 bar).

Corrosion resistance:

Depending on the area of use, corrosion protection measures may be necessary. The manufacturer suggests over-ground pipelines and fittings in rooms which do not normally require external corrosion protection.

They suggest exceptions in the following cases:

Contact with aggressive building materials such as nitrite, or materials containing ammonium.
In aggressive surroundings.

If external corrosion protection is required, the manufacturer recommends that the following regulations are followed:

DIN EN 806-2.
DIN 1988-200.
