Viking Johnson coupling UltraGrip DN050 48.0-71.0 mm

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 both sides of the UltraGrip coupling, 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 50 and has a size range from minimum 48 mm to maximum 71 mm on both sides. In addition, this coupling is suitable for drinking water up to PN 16 due to the gasket of EPDM on both sides.

Product Features

The UltraGrip coupling is designed to meet the requirements of EN 14525. This coupling is made of ductile iron with an rilsan nylon 11 coating, which makes the UltraGrip coupling highly resistant to abrasion and damage from chemicals or corrosion. 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. In addition, the UltraGrip coupling is suitable for angular deflection up to 8° (2x 4°) over the entire size range of the coupling.
