    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


    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.
