Raxofix

General

Flow-​optimised press connector system for potable water installations in acc. with DIN 1988 and DIN 50930‑6 as well as 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. In this way, widening or calibration of the pipe-​ends becomes superfluous and reduces the assembly times. The interaction between aerodynamic radii and minimal cross-​section narrowings ensure the lowest pressure losses in press systems for multilayer pipes. This allows a smaller dimensioning of potable water installations and reduces the pipeline volume.
SC‑Contur
All sizes with SC‑Contur – accidently unpressed connections become visible during filling the system. The SC‑Contur is certified and fulfils the requirements of the DVGW worksheet W 534, point 12.14, Connectors with forced leakage.
During leakage tests with water Viega guarantees the identification of unpressed connections in the pressure range 0.1 MPa–0.65 MPa, in the case of dry leakage tests with compressed air or noble gases from 22 hPa–0.3 MPa.

    Note
    The press connector system Raxofix 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 DVGW test mark is only valid for the use of original Viega parts - installation of non-​Viega parts is not permitted. The pipes conform to the recommendations of KTW (Plastic in potable water) of the German Federal Environmental Agency and the requirements of the DVGW worksheet W 270.
    Can be installed inaccessibly without restrictions in acc. with VOB-​C Point 3.2.7. Warranty and ZVSHK transferred liability agreement.

    • DVGW-​Reg.-No. DW-8501BU0124 / DW-8803CT0643

    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.
