Viking Johnson coupling UltraGrip DN400 398,2-442,0 mm A4

Viking Johnson offers a solution for connecting non-dedicated pipes of various materials with the UltraGrip series. The gripping mechanism provides maximum grip around the entire pipe circumference and resistance for axial loads. As the internal pressure in the pipe increases, the gripping mechanism can hold more end loads. In addition, UltraGrip can be converted to a flexible, non-restraint product that allows axial movement by removing the grippers.

Application

Various pipe materials can be connected to both sides of the UltraGrip coupling, including cast iron, ductile iron, steel, PVC, PE, GRP and asbestos cement. The UltraGrip coupling is restraint and is designed to connect pipes with different outside diameters. The connection of this coupling is DN 400 and has a size range from minimum 398,2 mm to maximum 442 mm on both sides. With a EPDM gasket on both sides, the coupling is suitable for drinking water up to PN 10.

Product Features

The UltraGrip coupling is designed to meet the requirements of EN 14525. The UltraGrip coupling is made of ductile iron with an rilsan nylon 11 coating. This makes the coupling resistant to abrasion or significant damage from chemicals or corrosion over a long period of time. In addition, the specially profiled gasket completely seals pipes, despite damage or corrosion on the pipes. A support liner for this coupling is recommended when used on a PE pipe. Furthermore, the UltraGrip coupling can accommodate angular deflection up to 8° (2x 4°) over the entire coupling size range.
