Gas valves

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 / 2.2 kPa / 22 mbar / 0.3 PSI
max. air pressure: 0.3 MPa / 300 kPa / 3 bar / 43.5 PSI

Sealing elements
HNBR (hydrogenated acrylonitrile butadiene rubber), yellow, pre-​assembled

Dimensions
D½ –2, size availability in accordance with the national regulations
