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 / 1 bar / 14.5 PSI
max. water pressure: 0.65 MPa / 6.5 bar / 94.3 PSI
min. air pressure: 22 hPa / 22 mbar / 0.3 PSI
max. air pressure: 0.3 MPa / 3 bar / 43.5 PSI
FKM (fluorocarbon rubber), matt black, pre-assembled
D⅜–4, size availability in accordance with the national regulations
The functional safety of Viega press connector systems depends primarily on the faultless condition of the press tools used. The Pressgun Press Booster is required for manufacturing Megapress S XL press connections. Viega press tools have to be regularly maintained by authorised service partners.
Areas of application
Industrial and plant engineering
Local and district heat systems as per AGFW FW 524 (after entry into the building, ≤ DN50)
Closed cooling and heating systems
Compressed air systems
Fire extinguishing and sprinkler systems (the required minimum and maximum wall thickness have to be observed)
Systems for technical gases (request required)
Use of the system for areas of application and media other than those described must be agreed in consultation with Viega! Detailed information about applications, restrictions and national standards and directives can be found in the product information, either printed or on the Viega website.

Material press connector
Note – Protection against external corrosion
Thanks to a zinc-nickel coating the press connectors are optimally protected against corrosion – e.g. when condensation forms in cooling systems.
The pipe being used should be protected with suitable corrosion prevention – observe manufacturer's information.
Pipes and pipe connectors should be insulated in the same way in accordance with the general rules of engineering.
Pressure gradient calculator
Web application for quick and simple calculation of pipeline dimensions for potable water, heating and gas supply lines with associated pressure loss tables across the entire system.
