Cold press pipeline fittings for use with steel gas pipes.
The piping system must not be used for fuel gases in accordance with DVGW G 260. The connectors may only be pressed with Megapress press rings and jaws.
Press connector fittings with connectors manufactured from non-alloy steel 1.0308 for seamless, welded, galvanized, epoxy resin-coated, industrially painted and black steel pipes in accordance with DIN EN 10255, DIN EN 10220/10216-1 or DIN 10220/10217-1.
The Hydrogenated Nitrile Butadiene Rubber (HNBR) sealing elements guarantee that the press connections have the required degree of sealing, even where the pipe surface is rough. Suitable for retrofit installations.
Sealing element:
A cutting ring, 1.4301 grade stainless steel separator ring and an HNBR profile sealing element are included in the bead of the press connector. The cutting ring cuts into the pipe during pressing and ensures a force-locked connection.
During insertion of the pipe, and later during the pressing, the separator ring protects the sealing element from damage.
Press connectors:
The press connectors are equipped with the Viega SC-Contur, which is a safety technology approved by Kitemark, and ensures that the connection is guaranteed to be leaking in an unpressed state. In this way, inadvertently unpressed connections are noticed immediately during a leakage test.
Viega MegaPressG fittings are offered in numerous configurations, including:
