The Viking Johnson AquaFast portfolio provides a comprehensive, high-performance piping solution designed to accommodate diverse pipeline diameters through two distinct lines. This advanced product range comprises the AquaFast 63mm to 315mm series and the AquaFast Large Diameter 355mm to 450mm series.
\n\n\n\n
Both product lines share a core engineering philosophy that prioritises effortless installation, robust connection reliability, and long-term asset protection across all operational conditions. By eliminating the need for specialist tools, extensive training, or internal support liners, AquaFast dramatically simplifies the joining of polyethylene and polyvinyl chloride pipes.

AquaFast: 63mm to 315mm
\n\n\n\n
The standard AquaFast series is specifically engineered to streamline both new pipeline construction and on-the-spot field repairs.
\n\n\n\n
This range features a unique pressure-sealing system combined with an enhanced gripping mechanism that ensures the fittings slide easily into position during assembly. Installers can easily position the product within narrow trenches or challenging environments because the smart design deliberately delays gripper engagement.
The jointing process requires only a standard spanner to tighten a minimal number of bolts, featuring just two bolts per fitting for sizes up to 125mm.
A built-in metal-to-metal positive stop serves as a visual indicator to confirm correct fitment, removing the need for torque wrenches and entirely preventing over-tightening.
Once fully installed, the system provides absolute end-load restraint that resists pipe pull-out, effectively negating the need for expensive concrete thrust blocks.
Furthermore, these couplings and flange adaptors accommodate both PE80 and PE100 polyethylene pipe materials across various standard dimension ratios without requiring an internal liner.
This versatile design makes the standard range an ideal solution for creating seamless transitional connections between polyethylene and metric polyvinyl chloride pipes.

AquaFast Large Diameter: 355mm to 450mm
\n\n\n\n
The AquaFast Large Diameter series expands these operational capabilities to larger infrastructure projects. This innovative range offers an efficient, all-weather alternative to traditional, time-consuming electrofusion and butt-fusion jointing methods.
\n\n\n\n
The large diameter fittings are carefully engineered with a high structural tolerance that easily accommodates oval pipes, eliminating the need for expensive and slow re-rounding tools in the trench.
Water utilities and distribution networks benefit significantly from this range because just ten product sizes cover a wide selection of multiple standard dimension ratios.
For long-term durability, the large diameter fittings feature a premier WRAS-approved black Rilsan Nylon 11 coating that delivers exceptional resistance to impact, abrasion, harsh chemicals, and severe weathering.
The advanced gripping mechanism ensures full end-load restraint and makes the assembly suitable for use in extreme climatic regions ranging from minus twenty degrees up to sixty degrees Celsius.
Manufactured under stringent quality management systems conforming to BSI ISO 9001, the range meets rigorous UK and European Water Regulations alongside international performance standards like BS EN 12842 and ISO 178875.

AquaFast 63mm – 450mm Brochure (10-2024 Issue 8) – English
AquaFast’s improved design makes fitting easier on oval or coiled pipes. With fewer bolts and no torque wrench required, installation is faster, simpler and demands less skill than traditional systems.
A built-in metal-to-metal positive stop removes the need for a torque wrench and prevents over-tightening, ensuring a perfect, consistent installation every time.
The resister feature delays gripper engagement, allowing installers to slide and reposition the fitting accurately—even in harsh or wet trench conditions.
AquaFast provides full end-load restraint and is engineered to meet WIS 4-24-01 Type 2 and ISO 14236.2, ensuring secure, long-lasting resistance to pipe pullout.
The patented gasket and metal component design features enable triple contact pressure responsive sealing, ensuring high performance sealing even after pipe wall relaxation.
