The Funke FHS Coupling that is easily able to withstand pressude of 1.5 bar is suitable for connecting wastewater pipes made of different materials, various outside diameters and surface structures. Depending on the clamping range, pipe connections with different outside diameters and/or nominal diameters are also possible. For example high temperature pipes DN40 (outside diameter 40mm) can be connected with cast iron pipes DN50 (outside diameter 58mm). The FHS Coupling can be installed both horizontally and vertically and can be used in the ground as well as under plaster. Pipes made of all common materials such as cast iron, steel, PP, PE, PVC, clay and other smooth or corrugated pipes can be joined in nominal diameter ranges from DN/OD 40 to DN/OD 110. The possible clamping ranges in the above nominal diameters are 40-65mm, 50-80mm and 75-110mm. The three-part swivel joint coupling consists of a special EPDM sealing element, two clamping clamps and a three-part, adaptable fixing
