Press connector fittings with connectors and pipes manufactured from 1.4401 and 1.4521 stainless steel material. Produced in accordance with DIN EN 10088, DIN EN 10312 and DVGW worksheet GW 541. System certification for connectors and pipes in accordance with DVGW worksheet W 534, for drinking water installations in accordance with DIN 1988. For dimensionally stable concealed and pre-​wall installations of manifold, and riser pipes in Viega component assembly.Sealing element:EPDM rubber, polished black, heat-resistant up to 110°C and not resistant against hydrocarbon solvent, chlorinated hydrocarbon solvents, turpentine or petrol.Press connectors:The press connectors have a circumferential bead in which the sealing element lies. The connector is deformed in front of and behind the bead, and permanently connected to the pipe during pressing. The sealing element is not deformed during pressing. Viega's distinctive hexagonal pressing pattern bonds fitting and pipe and provides the mechanical strength for the connection.The connectors may only be pressed with Viega press machines with constant pressing force (e.g. Pressgun 5, Picco, Pressgun 4E/ 4B).With SC‑Contur, any connections which remain un-pressed 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.Viega guarantees that unpressed connections are visible during a leakage test:With the wet leakage test in the pressure range from 0.1–0.65 MPa (1.0–6.5 bar).With dry leakage test in the pressure range from 22 hPa–0.3 MPa (22 mbar–3.0 bar).Viega Sanpress Inox fittings are offered in various configurations, including:Pipes, elbows and T-​pieces.Adapter pieces/ adapter elbows.Couplings and reductions.Flanges.Wall plates.Smartloop inliner technology; internal circulation pipes.Compensators.Stainless steel shut-off valves.Stainless steel ball valves.Free-flow and straight seat valves.Accessories.Pipes:Stainless steel, laser-​welded and manufactured from corrosion-​proof stainless steel:Material: 1.4401 (AISI 316L) (X5CrNiMo 17‑12-2), with 2.3% molybdenum for increased durability; yellow plugs.Material: 1.4521 (AISI 444) (X2CrMoTi 18‑2), with PRE-​value 24.1; green plugs.Corrosion resistance:The manufacturer suggests that the components should be protected against high concentrations of chloride generated by both the medium and by external factors. If external corrosion protection is required, the manufacturer recommends that the following regulations are followed:DIN EN 806-2.DIN 1988-200.Applications:Drinking water with less than 250 mg/L of chloride concentration (to DIN EN 806-1 and DIN 1717, in addition to DIN 1988, VDI/ DVGW 6023 and Drinking Water Ordinance (DWO).Heating/ radiator connection (see VDI 2035 sheets 1 and 2 and DIN EN 12828).Rainwater.Compressed air in compliance with EPDM sealing element at oil concentration: <25 mg/m³.

Sealing element:

EPDM rubber, polished black, heat-resistant up to 110°C and not resistant against hydrocarbon solvent, chlorinated hydrocarbon solvents, turpentine or petrol.

Press connectors:

The press connectors have a circumferential bead in which the sealing element lies. The connector is deformed in front of and behind the bead, and permanently connected to the pipe during pressing. The sealing element is not deformed during pressing. Viega's distinctive hexagonal pressing pattern bonds fitting and pipe and provides the mechanical strength for the connection.

The connectors may only be pressed with Viega press machines with constant pressing force (e.g. Pressgun 5, Picco, Pressgun 4E/ 4B).
