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:

Minimum air pressure: 22 hPa / 22 mbar / 0.3 PSI.
Maximum air pressure: 0.3 MPa / 3 bar / 43.5 PSI.

Sealing elements:

HNBR (hydrogenated acrylonitrile butadiene rubber), yellow, 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 authorized service partners.
