1. Marine Certificates of Viega Press Connectors

2. Press connector with SC‑Contur

The Viega press connector system featuring the SC-Contur function enables detection of unpressed connections, as they become visibly leaky when the system is filled/charged. Viega guarantees detection of unpressed connections within the following pressure ranges:

Test medium: Water

• Minimum pressure: 0.1 MPa (100 kPa / 1 bar / 14.5 PSI)
• Maximum pressure: 0.65 MPa (650 kPa / 6.5 bar / 94.3 PSI)

Test medium: Air

• Minimum pressure: 22 hPa (2.2 kPa / 22 mbar / 0.3 PSI)
• Maximum pressure: 0.3 MPa (300 kPa / 3 bar / 43.5 PSI)

In addition, the Sanpress Inox press connector system is designed for nominal pressure PN 16.

3. Dimensions

Size range: d15 – 108.0mm

4. Piping Applications

The Sanpress Inox press fitting system is suitable for the following piping systems/applications:

• Potable water
• Heating / radiator connections
• Rainwater
• Compressed air systems
• Agriculture
• Industrial applications
• Fire extinguishing systems (DIN 14462) wet
• Fire extinguishing systems (DIN 14462) dry and dry/wet (≤ DN65)
• Sprinkler systems (VdS CEA 4001) wet, wet/dry, dry

Note: System components must be protected against high chloride concentrations originating from the medium and/or external influences. For use outside the above applications/media, or if there is any doubt about the correct material selection, please contact Viega.
