Long Term Performance
Product is third party accredited to BS8561:2021 which ensures end user confidence.
When used on polyethylene pipe the product achieves a Type 2 end load performance as defined in WIS 4-24-01 and ISO 17855.
Cost Effective Pipelines
UltraGrip restraint system is equipped with a unique gripping technology that allows consulting engineers to design more cost effective pipelines, without the need for external restraints, like for example thrust blocks.
Simple to Fit
Supplied with captive studs, these can be bolted up by a technician using a single spanner making UltraGrip ideal for use in all trench conditions. Plus there is no requirement to re-torque or revisit after initial bolt-up.
50 Year Design Life
Along with extensive long term testing, and high performance gasket, the stainless steel bolts coated with dry film lubricant provide excellent corrosion resistance against degradation and maximises the longevity of the product
No Leakages
A proven high performance wide tolerance, EPDM gasket technology which Viking Johnson has been utilising for more than 40 years.
Ease of Handling
Installation made simple with incorporated lifting eyes for ease of manoeuvrability.
Upsized for the challenges ahead
Versatile Fittings
UltraGrip is the perfect choice for water and wastewater applications for projects below or above ground*. It is the ideal solution for joining diverse pipe materials such as Ductile Iron, Cast Iron, Steel, PE, MOPVC and Asbestos Cement.
*UltraGrip can be used in above ground applications, where it is not exposed to direct sunlight, and falls within the 40 degrees operating temperature range (between -20 and +60).
Repair & Maintenance
Infrastructure Projects
Ease of Installation
UltraGrip is easy to install on site even in narrow trenches. Installation is made simple with lifting eyes added for ease of manoeuvrability. The product is preassembled to allow for quick positioning over the top and bottom tolerance pipe with captive studs requiring only a single spanner for tightening when dealing with tricky site conditions.
Plus after installation there is no requirement to re-torque or to revisit after initial bolt up.
Exceptional versatility for large scale infrastructure projects
Exhaustive Testing & Accreditations
Extensive testing & quality endorsements
Viking Johnson products undergo vigorous testing regimes to ensure a long life, these includes finite element analysis (ANSYS) as well as extensive testing witnessed by third party test houses to verify compliance with the long term testing as defined in BS8561:2021, when used on Ductile Iron, Steel, PE, MOPVC, Cast Iron, and Asbestos Cement. For PE UltraGrip fittings also achieve an axial end load equivalent of a Type 2 performance as defined and tested by IGN 4-01-02:2017.
In addition, the performance has been validated through extensive physical testing, including hydrostatic, pull-out, leak tightness, strength and resistance to distortion tests. Furthermore, pressure tests with shear load have been carried out on grooved pipe, to simulate typical corrosion and ground loading found in old pipelines.
Also the products can mobilise restraint and seal effectively in all situations, giving installers and end users confidence the products will perform.
