Industries
Engineered Performance
Technical advantages built into every unit in this range.
High Crush Resistance
SN4 and SN8 stiffness classes available — engineered to withstand heavy traffic loads and soil compaction pressures at burial depths up to 6m.
Electrical Non-Conductivity
Inherently non-conductive PVC material eliminates electrolytic corrosion and provides safe cable segregation in high-voltage environments.
Smooth Internal Bore
Precision-extruded smooth internal surface minimises cable-pulling friction, enabling longer cable runs with reduced installation effort.
Wide Temperature Range
Stable performance from −10°C to +60°C, suitable for Saudi Arabia's extreme thermal cycling conditions in both desert and coastal environments.
Chemical Resistance
Resistant to acids, alkalis, oils, and industrial solvents — providing lasting protection in contaminated soil conditions and industrial zones.
Push-Fit Socket System
Integrated push-fit rubber-ring socket joint for fast, tool-free installation. Pre-formed bell ends ensure leak-free, repeatable connections.
