Material construction

Jacket lining:

  • Warp: High-tenacity polyester
  • Weft: Polyamide; circular woven
  • The special jacket construction ensures outstanding adhesion and much lower pressure loss compared to a 100% polyester jacket lining
  • Totally embedded in the reinforced rubber, offering optimum protection against mechanical damage


Rubberized lining and jacket:

  • Very high-grade NBR/PVC compound, extruded through the weave in a special one-step production process
  • Special additives in the compound guarantee outstanding resistance to aging and ozone
  • Inside: Very smooth for minimal pressure loss
  • Outside: Ribbed for excellent abrasion resistance, protection against contact heat


  • Highly resistant to abrasion, tough and durable
  • Resistant to oil, gasoline and chemicals (see resistance table)
  • Resistant to heat, aging and ozone
  • Very low pressure loss and minimal elongation
  • Very lightweight, flexible and pressure-resistant compared to mandrel-wound industrial hoses
  • No cleaning or drying required
