Viega Smartpress


Flow-​optimised press connector systems with multi-​layer pipes for potable water and heating installations. Tested in acc. with DVGW worksheet W 534.

Press connectors

Safe and fast processing without calibration of the pipe ends through O-​ring-​free press technology in all dimensions. Streamlined radii and minimal cross-​section narrowings ensure minimal pressure losses. This allows a smaller dimensioning of potable water installations and reduces the pipeline volume.
All sizes with SC‑Contur – inadvertently unpressed connections are noticed during leakage test.
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.

    Areas of application
    Potable water

    The use of the systems for other areas of use and media than those described must be approved by the Viega Service Center.

    Operating conditions
    Potable water installations
    • Operating temperature max. 70 °C
    • Operating pressure max. 1.0 MPa
    Heating installations
    • Operating temperature max. 80 °C
    • Operating pressure max. 1.0 MPa

    Irrelevant of the direction of flow, mixed installations are permitted.

    The press connector system Smartpress is suitable for the creation of potable water installations according to DIN 1988‑200 and EN 806‑2 in consideration of the selection of material in accordance with DIN EN 12502‑1 and DIN 50930‑6. When used for other areas of use and when in doubt about the right selection of material, please contact Viega.
    The system components should be protected against high concentrations of chloride generated by both the medium and by external factors.
    Only use original Viega parts – installation of non-​Viega parts is not permitted.

    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.
