Industries
Engineered Performance
Technical advantages built into every unit in this range.
Potable Water Safe
100% non-toxic material composition certified for potable water contact — no leaching, no taste or odour impartation, fully WRAS and SASO approved.
Multi-Pressure Class
PN6, PN10, PN12.5, and PN16 classes cover working pressures from 6 to 16 bar — precise selection for every network zone.
50+ Year Service Life
Designed service life exceeding 50 years under standard operating pressure and temperature conditions, with minimal maintenance and no corrosion.
UV & Corrosion Resistance
Carbon black UV stabilization for above-ground applications combined with inherent corrosion resistance eliminates the need for cathodic protection systems.
Fast Rubber Ring Assembly
Spigot and socket rubber ring joint for rapid field assembly without specialised tools — jointing rate of 40+ joints per crew per day achievable.
Dimensional Precision
Tight dimensional tolerances (±0.5% OD) ensure consistent fitting compatibility and hydraulic performance across the entire product range.
