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

Various pipe materials can be connected to the UltraGrip coupling, including cast iron, ductile iron, steel, PVC, PE, GRP and 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 32 and has a size range from a minimum of 36 mm to a maximum of 46 mm. The other connection is DN 40 and has a size range from a minimum of 43,5 mm to a maximum of 63,5 mm.

Product Features

The UltraGrip reducing coupling is designed to meet the requirements of EN 14525. The UltraGrip reducing coupling is made of cast iron with a rilsan nylon 11 coating. This makes the coupling resistant to abrasion or significant damage from chemicals or corrosion. Due to the specially profiled gasket of the coupling, even pipes that are damaged or affected by corrosion can be completely sealed. 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.
