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

The UltraGrip coupling allows you to connect the coupling to various pipes, including cast iron, ductile iron, steel, PVC, PE, GRP, asbestos cement. The gasket of this coupling is made of EPDM, making the coupling 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 125 and has a size range from a minimum of 132,2 mm to a maximum of 160,2 mm. The other connection is DN 150 and has a size range from a minimum of 158,2 mm to a maximum of 192,2 mm.

Product Features

The UltraGrip reducing coupling is designed to meet the requirements of EN 14525. This reducing coupling is made of cast iron with a rilsan nylon 11 coating, making it highly resistant to abrasion and damage from chemicals or corrosion. 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 reducing coupling is capable of accommodating an angular deflection up to 8° (2x 4°) over the entire size range.
