Viega Profipress bend 90° 28 Copper/bright 291686

Press connector system with press connectors made of copper and gunmetal tested in acc. with DVGW worksheet W 534 with DVGW test seal and pipes made of copper in acc. with EN 1057 in acc. with DVGW worksheet GW 392.Suitable for drinking water installations in acc. with DIN 1988.For dimensionally stable concealed and pre-wall installations of manifold and riser pipes in Viega component assembly.Press connectorsAll 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 connectionSealing elementsEPDM, black (ethylene-propylene-dien-monomer rubber), up to 110 °C, not resistant against hydrocarbon solvent, chlorinated hydrocarbon solvents, turpentine, petrolDimensions/MaterialStandard sizes: d 12, 15, 18, 22, 28, 35, 42, 54 made of copperXL sizes: d 64.0, 66.7, 76.1, 88.9, 108.0 made of copperXL sizes: d 76.1, 88.9, 108.0 made of gunmetalPress connectors with threaded connection made of gunmetal: d 12–54, 76.1–108.0Press connectors with threaded connection made of copper: d 64.0Areas of applicationDrinking waterHeating/Radiator connectionRainwaterCompressed air, noble gasesCooling water pipelinesIndustryPlant engineeringSpecial applicationswith EPDM sealing element, factory-fitted•stationary sprinkler-extinguishing systems - with VdS certificate G 4980009 for the sizes DN20-DN50 in connection with copper pipes in acc. with EN 1057 R290 (hard)•Solar systems with flat collectorswith FKM sealing element (accessories)•Solar systems with flat/vacuum collectors•District heat suppliers and low pressure steam systemsUse of t
