Marking Manufacturer, pipe dimension, batch, green dot on press end, interchangeable green, red or blue media marking 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: Min. water pressure: 0.1 MPa / 100kPa / 1 bar / 14.5 PSI Max. water pressure: 0.65 MPa / 650kPa / 6.5 bar / 94.3 PSI Min. air pressure: 22 hPa / 2.2 kPa / 22 mbar / 0.3 PSI Max. air pressure: 0.3 MPa / 300kPa / 3 bar / 43.5 PSI Sealing elements EPDM (ethylene propylene diene rubber), black, pre-assembled FKM (fluorocarbon rubber), matt black, pre-assembled The use of FKM sealing elements in potable water and gas installations is not permitted!
