Viega Smartpress


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.

Dimensionally stable multi-​layer pipes d 16–63 in the versions: shiny, in protective pipe and pre-​insulated for a quick and easy installation

d 16–63
Elbows, T-​pieces and coupling made of stainless steel 1.4401
Press connectors with threaded connection and reduces made of gunmetal CC499K

d 16–25
Elbows, T-​pieces, coupling and manifolds made of PPSU only for potable water and heating installations

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. 8°C
  • Operating pressure max. 1.0 MPa

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

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.
