Flow-optimised press connector system with press connectors made of gunmetal or silicon bronze (change of material due to the current switch of production from gunmetal to the Viega worldwide uniform silicon bronze alloy) and pipes made of stainless steel 1.4401 and 1.4521. Free of paint-wetting impairment substances (PWIS-free) such as silicone, grease or oil. Especially suitable for the use of piping installations in paint shops. 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. For protection pipes are equipped with pipe plugs. The pressing force is located before and behind the sealing element seat. Suitable for concealed and pre-wall installations of riser pipes and floor installations.
Marking Manufacturer, pipe dimension, batch, blue dot on the press end, yellow pipe plug for 1.4401, green pipe plug for 1.4521, detachable orange label as press indicator from d64.0
Press connector with SC‑Contur Inadvertently unpressed connections become visibly leaky when the system is filled. Viega guarantees the detection of unpressed connections in the following pressure ranges: min. water pressure: 0.1 MPa / 1 bar / 14.5 PSI max. water pressure: 0.65 MPa / 6.5 bar / 94.3 PSI min. air pressure: 22 hPa / 22 mbar / 0.3 PSI max. air pressure: 0.3 MPa / 3 bar / 43.5 PSI
Sealing elements EPDM (ethylene propylene diene rubber), black, pre-assembled
Tools The functional safety of Viega press connector systems depends primarily on the faultless condition of the press tools used. For the manufacture of press connections, Viega recommends the use of Viega press tools. Viega press tools have to be regularly maintained by authorised service partners.
Areas of application Potable water Rainwater Compressed air systems Agriculture Industrial applications
Note The press connector system Sanpress LF 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 according to the evaluation basis for metallic materials in contact with potable water of the Umweltbundesamt (UBA) (Federal Environment Agency). 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. Detailed information about applications, restrictions and national standards and directives can be found in the product information, either printed or on the Viega website.
