Press connector systems with press connectors and pipes made of non-alloy steel 1.0308 (E235), in acc. with EN 10305-3, externally galvanised with a zinc layer thickness of 8–15 µm (blue chromatised).
Press connectors
All sizes with SC-Contur – connections, which remain unpressed become visible when the system is filled. The SC-Contur is certified and fulfils the requirements of DVGW worksheet W 534, point 12.14, connectors with forced leakage.
During leakage tests with water, Viega guarantees the identification of unpressed connections in the pressure range 0.1 MPa–0.65 MPa, in the case of a dry leakage test with compressed air or noble gases from 22 hPa–0.3 MPa.
Marking
Red symbol (to prevent confusion with Sanpress Inox (stainless steel) articles) »Not for drinking water installations«
Sealing elements
EPDM, black (ethylene-propylene-dien-monomer rubber);not resistant against hydrocarbon solvent, chlorinated hydrocarbon solvents, turpentine, petrol, FKM, dull black

Note
Megapress is suitable for
•Fire extinguisher and sprinkler units (required minimum wall thickness and maximum wall thickness need to be considered)
•For pipes in acc. with DIN EN 10220 / DIN EN 10216-1 / DIN EN 10217-1:
raw line 1: D⅜–D4
raw line2: external-Ø 57,0 raw line 3: external-Ø44,5 The Megapress system is not suitable for •combustible gases in acc. with DVGW worksheet G 260 •Drinking water installations and other open systems Megapress components may only be used with components that belong to the system! Protection against external corrosion Thanks to a high-quality zinc-nickel coating the press connectors are optimally protected against corrosion - e.g. when condensation water forms in cooling systems. The pipe being use should be protected with suitable corrosion prevention measures - observe manufacturer's information. Pipes and connectors should be insulated in the same way in acc. with the general rules of engineering. Use of press tools The functional safety of the Viega press connector systems is primarily dependent on the perfect condition of the press tools and press machines used. For this reason, for the production of press connections, we recommend the use of Viega press tools and their regular inspection by authorised service points. Technical data Press connectors and components are constantly being optimised.
