Viking Johnson coupling UltraGrip DN350 352,2-396,0 mm

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

The UltraGrip coupling can be connected to various pipes, 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 350 and has a size range from minimum 352,2 mm to maximum 396 mm on both sides. In addition, this coupling is suitable for drinking water up to PN 10 due to the gasket of EPDM on both sides.

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, making the coupling resistant to abrasion or damage from corrosion or chemicals. In addition, pipes can be completely sealed by the specially profiled gasket, even when they are damaged or affected by corrosion. 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.
