Flow-optimised press connector system made of copper (99.9 % Cu-DHP), gunmetal or silicon bronze for copper pipes. 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. 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, approval markings (DVGW), yellow dot on press end, yellow rectangle with inscription »Gas MOP 5 / GT1«, detachable orange label as press indicator from d64.0
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
Dimensions d12–64.0, size availability in accordance with the national regulations
Tools The functional safety of Viega press connector systems depends primarily on the faultless condition of the press tools used.
