Hs-Umformtechnik developed the aluminium die-cast coupling type DVK 6. This coupling is ideal wherever a gas-tight connection of tubes, pipe bends and branch pipes is needed. The coupling DVK 6 stands for a quick, safe and economic installation. There are no additional welding works needed, it is easily to be dismantled and all connecting pieces and tubes can be reused. The coupling can be used both for pressure and vacuum conveying, offering besides its technical advantages an easy installation while being vacuum-proof until 0.6 bar and pressure-resistant until 6 bar. At present this aluminium die-cast coupling is available in lengths of 100 mm (vacuum) and 150 mm (pressure). Available are diameters from 38 to 65 mm. The coupling DVK 6 consists of the aluminium body, material AlMgSi 0.5 F22, a dented gasket, a grounding strip for continuous electrical conductivity, corrugated-head screws and galvanized nuts.
