Propress

Inadvertently unpressed connections are noticed immediately during a leakage test.
Viega guarantees the detection of unpressed connections in the following pressure ranges:
min. water pressure: 0.1 MPa / 100 kPa / 1 bar / 14.5 PSI
max. water pressure: 0.65 MPa / 650 kPa / 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 / 300 kPa / 3 bar / 43.5 PSI

Sealing elements for press connection
EPDM (ethylene propylene diene rubber), black, pre-​assembled

Dimension
DN15–100, 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. Viega recommends the use of Viega press tools for pressing Viega press connectors. Viega press tools have to be regularly maintained by authorised service partners.
