Protectaflex - Dual Containment Hose

Protectaflex is the next generation dual containment hose system, offering all the benefits of existing products but in a smaller, lighter, and more manageable format.

Due to its lighter weight & reduced packaging, Protectaflex offers a significant reduction in shipping weight, lowering your carbon footprint.

The durable PU outer is UV stable and offers excellent clarity for visual inspection.
It is also manufactured from a WRAS approved material.

Features & Benefits

  • Lower cost. Up to 60% cheaper than Draw-Flex, Hose in Hose Dual Containment
  • Lower shipping and storage costs. Up to 48% lighter than Draw-Flex, Hose in Hose Dual Containment
  • Better flexibility & lower bend radius, easier to handle & easier to install than current dual contained product
  • Fittings can be swaged on, offering a comprehensive coupling, eliminating the risks of clips and the need for expensive bespoke dual contained fittings. Only one standard hose tail fitting required per end
  • Reduced packaging and fully recyclable resulting in a lower carbon foot-print
  • System designed catch-pots which enable the outer containment to be terminated inside the catch-pot
  • Ideal for temporary lines as no catch-pot is required
  • Potential to have a continuous run of inner dosing hose even with a catch-pot
  • In tests the PU outer did not distort when the inner hose burst
  • We can also offer Reinforced PVC, Hytrel Lined VendHose & PTFE as inner hoses.
