Technical data based on water. For air pressure the minimum safety ratio is 1:4. Depending on the application our product can be operated with a maximum working pressure up to 50% of the bursting pressure. Consult factory for approval! It is important to note, that the technical data for pressure are only valid for hose and not for hose assembly with couplings!

To obtain maximum lifetime the end pull under working conditions should not exceed 1/3 of the breaking strength

Textile reinforcement:

  • warp: high tenacity polyester
    weft: polyamide, circular woven
  • the special weaving design offers a high tensile strength, superior adhesion level and flow performance compared to an all polyester weave
  • totally embedded in the rubber compound, excellent protected against mechanical damage

Lining and cover:

  • special high grade formulated NBR / PVC compound extruded through the weave in
    a unique one step production process
  • special additives in the compound guarantee superior UV and ageing resistance
  • inside: very smooth for minimum friction loss
  • outside: ribbed for good abrasion resistance and protection against contact heat
