Viking Johnson's UltraGrip Series is designed to join non-dedicated pipes of various materials. The gripping mechanism provides maximum grip around the pipe circumference, thereby resisting axial loads. As the internal pressure in the pipe increases, the gripping mechanism can also hold more end load. Because the grippers are removable, UltraGrip can also be converted to a flexible, non-restraint product that allows for axial movement.

Application

Both sides of the UltraGrip coupling can be connected to various pipe materials including cast iron, ductile iron, steel, PVC, PE, GRP and asbestos cement. This coupling is equipped with an EPDM gasket on both sides, making it suitable for drinking water up to PN 16. This UltraGrip reducing coupling is a restraint coupling, which is designed to connect pipes with different outer diameters. One connection of the coupling is DN 175 and has a size range from a minimum of 192,2 mm to a maximum of 226,9 mm. The other connection is DN 200 and has a size range from a minimum of 218,1 mm to a maximum of 256 mm.

Product Features

The UltraGrip reducing coupling is designed to meet the requirements of EN 14525. To prevent abrasion or significant damage from chemicals or corrosion, UltraGrip reducing couplings are made of cast iron with a rilsan nylon 11 coating. Even pipes that are damaged or corroded are completely sealed by the specially profiled gasket of the coupling. A support liner for this coupling is recommended when used on a PE pipe. Furthermore, the UltraGrip reducing coupling can accommodate angular deflection up to 8° (2x 4°) over the entire size range.
