Material construction

Jacket lining:

  • High-tenacity polyester yarn, circular woven
  • Specially designed for high continuous working pressures, high tensile strength and very little elongation under pressure
  • Totally embedded in the polyurethane, offering optimum protection against mechanical damage


Lining and jacket:

  • Thermoplastic polyether polyurethane, extruded through the weave in a special one-step production process
  • Highly resistant to abrasion, 4–5 times longer service life than nitrile hoses
  • Inside: Very smooth for minimal pressure loss
  • Outside: Very smooth for good flexibility


  • Outstanding abrasion resistance
  • Extremely tough, hard-wearing and durable
  • Extremely high tensile strength
  • Resistant to aging and ozone
  • Lightweight and easy to use compared to material transport hoses
  • Stays flexible at cold temperatures
