Viking Johnson AquaFast

AquaFast’s unique pressure sealing system offers a simple and reliable solution to connect polyethylene (PE) and 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.

From start to finish, AquaFast offers benefits to the installer. The fittings come fully assembled; no need to chamfer pipe ends or use a support liner on PE or thin walled PVC pipe. Furthermore, it can be installed in all weather conditions. Thus, there is no need for shelters and it is therefore ideal for on-the spot repairs. The enhanced AquaFast design offers precise control over activation of the grippers. This ensures improved functionality whilst undertaking a repair even in harsh trench conditions, with no need to dismantle on oval or coiled pipe. AquaFast can also be used in wet or submerged applications.

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.

AquaFast couplings and flange adaptors are available from 63mm to 315mm OD. They are designed to work on PE80 / PE100 PE Pipe SDR 11, 17 and 17.6 without a support liner. AquaFast can also be used to connect metric PVC pipe and is therefore ideal for PE/PVC transitional connections.
