Viega Coupling PB 16 mm gunmetal

Flow-optimised press connector system for drinking water installations in acc. with DIN 1988 and DIN 50930-6 as well as heating installations, tested in acc. with DVGW worksheet W 534.Press connectorsSafe and fast processing without calibration of the pipe ends through O-ring-free press technology in all dimensions. In this way, widening or calibration of the pipe-ends becomes superfluous and reduces the assembly times. The interaction between aerodynamic radii and minimal cross-section narrowings ensure the lowest pressure losses in press systems for multilayer pipes. This allows a smaller dimensioning of drinking water installations and reduces the pipeline volume.SC-ConturAll 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 MPa0.65 MPa, in the case of a dry leakage test with compressed air or noble gases from 22 hPa0.3 MPa.MarkingGreen dot on the press connectionPipesRaxofix PE-Xc/Al/PE-Xcdimensionally stable, oxygen-proof in acc. with DIN 4726, greyRaxofix PE-Xcflexible, blackDimensionsPress connectors and pipesRaxofix-PE-Xc/Al/PE-Xc: d 16/20/25/32/40/50/63Raxofix PE-Xc: d 16/20Areas of application PE-Xc/Al/PE-XcDrinking waterHeatingRainwaterCompressed airAreas of application PE-XcRainwaterDrinking waterUse of the system for application areas other than those described here must be agreed with Viega Service Center.Operating conditionsDrinking water installationsOperating temperature max. 70 COperating pressure max. 1.0 MPaHeating installationsOperating temperature max. 80 COperating pressure max. 1.0 MPaIrrelevant of the direction of flow, mixed installations are permitted.NoteThe DVGW test mark is only valid f
