Flow-optimised press connector system made of non-alloy steel 1.0308 with an externally galvanised zinc-nickel coating for black, galvanised, industrially painted and powder-coated steel pipes. Press connectors with stainless steel cutting ring to ensure the mechanical strength of the connection. Suitable for concealed and pre-wall installations of riser pipes and floor installations.
Marking Manufacturer, pipe dimension, batch, black dot on press end, black rectangle with symbol »Not approved for potable water installations«, orange/black detachable label as press indicator
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 water, compressed air or inert gases: 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), profile sealing element , black, pre-assembled
Dimensions D⅜–2, external Ø 38.0(DN32), external Ø 44.5 (DN40), external Ø 57.0 (DN50), 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. 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 Industrial and plant engineering Closed cooling and heating systems Compressed air systems Fire extinguishing and sprinkler systems (the required minimum and maximum wall thickness have to be observed) Systems for technical gases (request required)

Protection against external corrosion Thanks to a zinc-nickel coating the press connectors are optimally protected against corrosion – e.g. when condensation forms in cooling systems. The pipe being used should be protected with suitable corrosion prevention – observe manufacturer's information. Pipes and pipe connectors should be insulated in the same way in accordance with the general rules of engineering.
