Overview
HPFLEX® Heavy Duty corrugated conduit is manufactured in Australia to the highest standards with a 25-Year warranty*. Our conduit conforms to AS/NZS2053.5:2001 and is manufactured with B.E.P certified material. HPFLEX® is available from 16mm to 63mm (external diameter) and 80mm (internal diameter). Unplasticised PVC is a cost-effective polymer with high resistance to impact, water, weather, chemicals and corrosive environments. Due to its orange colour and high compression strength, HPFLEX® Heavy duty is ideal for underground electrical installations requiring the concealment and protection of electrical cables. Our heavy-duty is also UV stabilised to ensure strength and stability if subject to Australia’s harsh UV rays.
16mm to 63mm conforms to AS/NZS2053.5-2001 & Conforms to IEC 61386-22:2021 4.4.2.1
80mm Conforms to IEC 61386-22 4.4.2.1.2.2
