For connecting non-dedicated pipes of different materials, the UltraGrip series from Viking Johnson is an excellent solution. The gripping mechanism ensures maximum grip around the entire pipe circumference and is therefore resistant to axial loads. With increasing internal pressure, the gripping mechanism can hold more end loads. In addition, UltraGrip can be converted into a flexible, non-restraint product with axial movement by removing the grippers.

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. With an EPDM gasket on both sides, the coupling reducer coupling is 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 200 and has a size range from a minimum of 218,1 mm to a maximum of 256 mm. The other connection is DN 250 and has a size range from a minimum of 266 mm to a maximum of 310 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. In addition, even damaged and corroded pipes can be completely sealed by the specially profiled gasket. A support liner for this coupling is recommended when used on a PE pipe. Furthermore, within the entire size range of the UltraGrip reducing coupling, an angular deflection of up to 8° (2x 4°) is possible.
