    Press connector with SC‑Contur
    Inadvertently unpressed connections are noticed immediately during a leakage test.
    Viega guarantees the detection of unpressed connections in the following pressure ranges with compressed air or inert gases:
    min. air pressure: 22 hPa / 22 mbar / 0.3 PSI
    max. air pressure: 0.3 MPa / 3 bar / 43.5 PSI

    Sealing elements
    HNBR (hydrogenated acrylonitrile butadiene rubber), yellow, pre-​assembled


    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
    Natural gas/liquid gas
    Heating oil
    Diesel fuel

    The system components should be protected against high concentrations of chloride generated by both the medium and by external factors. Use of the system for areas of application and media other than those described must be agreed in consultation with Viega! Detailed information about applications, restrictions and national standards and directives can be found in the product information, either printed or on the Viega website.
