Flow-optimised press connector system made of non-alloy steel 1.0308 with an externally galvanised zinc-nickel coating for black, galvanised, industrially painted and powder-coated steel pipes. Press connectors with stainless steel cutting ring to ensure the mechanical strength of the connection. Suitable for concealed and pre-wall installations of riser pipes and floor installations.
Marking Manufacturer, pipe dimension, batch, white dot on press end, black rectangle with symbol »Not approved for potable water installations«, detachable white label as press indicator
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
Sealing elements FKM (fluorocarbon rubber), matt black, pre-assembled
Dimensions D⅜–4, 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. 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)
Note 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.
Note – Standards and approvals Suitable for steel pipes in accordance with EN 10255, EN 10220 / EN 10216‑1, EN 10220 / EN 10217‑1. For use in heating systems, observe VDI Regulation 2035 and DIN EN 12828. Not suitable for fuel gases in accordance with DVGW Worksheet G 260 and potable water installations, as well as other open systems.

Press connector material Steel 1.0308
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.
