Sanpress Inox LF

General

Sanpress Inox LF

Press connector system (labs-​free) with press connectors and pipes made of stainless steel material no. 1.4401 and 1.4521 in acc. with DIN EN 10088, DIN EN 10312, DVGW worksheet GW 541, system registration for connectors and pipes in acc. with DVGW worksheet W 534 for potable water isntallations according to DIN 1988. For dimensionally stable concealed and pre-​wall installations of manifold and riser pipes in Viega component assembly.

The press connector system Sanpress Inox LF is free from paint wetting destructive substances (labs) as silicone, fat, oil etc. and is therefore especially suitable for the use of pipeline installations in paint shops.


Press connectors
All sizes with SC‑Contur – accidently unpressed connections become visible during filling the system. The SC‑Contur is certified and fulfils the requirements of the 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 dry leakage tests with compressed air or noble gases from 22 hPa–0.3 MPa.

Use of press tools
The functional safety of the Viega press connector systems primarily depends 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. If required, the current Z and installation dimensions can be obtained from the download area of the Viega homepage: www.viega.com/downloads
