Megapress Stainless 316

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 / 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
EPDM (ethylene propylene diene rubber), black, pre-​assembled

Notice
The sealing materials of the press connector system are subject to thermal ageing, which depends on the media temperature and the operating time.
The higher the media temperature, the faster the thermal ageing of the sealing material progresses.
In the case of special operating conditions, e.g. industrial heat recovery systems, it is necessary to compare the specifications of the appliance manufacturer with the specifications of the press connector system.
Before using the press connector system beyond the areas of application described or if in doubt about the correct selection of material, please contact Viega.

Dimensions
D½–4, 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. The Pressgun Press Booster is required for pressing Megapress Stainless 316 XL press connectors. Viega press tools have to be regularly maintained by authorised service partners.

Areas of application
Industrial and plant engineering
Cooling and heating systems
Compressed air systems
Rainwater
Agriculture
Systems for technical gases (request required)

Note
When used for other areas of use and when in doubt about the right selection of material, please contact Viega. The system components should be protected against high concentrations of chloride generated by both the medium and by external factors.
