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 MPa-0.65 MPa  in the case of a dry leakage test with
compressed air or noble gases from 22 hPa-0.3 MPa.MarkingGreen dot on the press
