Sanpress

Flow-​optimized 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.

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.

Marking:

Manufacturer, pipe dimension, batch, green dot on 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:

• Minimum water pressure: 0.1 MPa / 1 bar / 14.5 PSI.
• Maximum water pressure: 0.65 MPa / 6.5 bar / 94.3 PSI.
• Minimum air pressure: 22 hPa / 22 mbar / 0.3 PSI.
• Maximum 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 authorized service partners.
