Viking Johnson AquaFast - Pressure Sealing System
AquaFast’s unique pressure sealing system offers a simple and reliable solution to connecting polyethylene & PVC pipe. In addition, an enhanced gripping mechanism offers end load restraint, resisting pipe pull out. No special skills or tools are required making installation effortless and quicker than other systems.
On-the-spot Repairs
From start to finish, AquaFast offers benefits to the installer. The fittings come fully assembled; no need to chamfer pipe ends nor use a support liner on PE or thin walled PVC pipe. It can be installed in all weather conditions, there is no need for shelters so it is ideal for on-the spot repairs. The enhanced AquaFast design offers precise control over activation of the grippers ensuring improved functionality while undertaking a repair, even in harsh trench conditions, with no need to dismantle on oval or coiled pipe. In fact it can also be used in wet or submerged applications.
Simple Jointing
With fewer bolts to fasten – only two per fitting up to 125mm – and minimum bolt tightening using a standard spanner, the installation is further simplified by the easy alignment of bolt holes and a positive stop during bolt tightening ensuring optimum assembly every time. This metal-to-metal positive stop inhibits over tightening, removing the need for a torque wrench.
Transitional Connections
AquaFast couplings & flange adaptors are available from 63mm to 315mm OD. They are designed to work on PE80 / PE100 PE Pipe SDR 11, 17 & 17.6 without a support liner and can also be used to connect metric PVC pipe so AquaFast is ideal for PE/PVC transitional connections.
- Improved design for easy alignment especially on oval and coiled pipe
- New Gripper mechanism provides greater flexibility, even in harsh and wet trench conditions to correctly align pipework
- Progressive gripping and pressure responsive sealing technology ensures high performance even after pipe wall relaxation
- AquaFast is ideal for small diameter pumped sewerage pipelines - as a support liner is not required.
- No need to dismantle before use, simply slip into place and tighten
- Slip-on coupling without central obstruction makes it easier to make repairs to existing pipelines
- Supplied as standard with EPDM gasket approved by WRAS for use with potable water
- Corrosion protection - Metal components are coated with Rilsan Nylon 11 which is WRAS approved for use with potable water.
- Dual function - can be used to connect PE80/100 and Metric PVC - ideal for PE/PVC transitional connections.
Improved design enables easier fitting on oval or coiled pipes. With fewer bolts to fasten and no torque wrench needed, AquaFast requires less skill and significantly less time and effort to install compared to other systems.
Positive StopMetal - to -metal positive stop removing the need for a torque wrench meaning less skill is needed to install and ensures the perfect installation every time.
Easy Adjustment on PipeThe resister enables the installer to adjust the fitting position over the pipe even in harsh trench conditions through delayed engagement of the gripper.
Resists PulloutFully restrained fitting, designed to meet the performance requirements of WIS 4-24-01 Type 2 and ISO 14236.2.
Unique 3-way Pressure Sealing SystemThe patented gasket and metal component design features enable triple contact pressure responsive sealing, ensuring high performance sealing even after pipe wall relaxation.
