Material construction

Fabric insert:

  • high tenacity polyester yarn, circular weave
  • heavy duty fabric construction for high continuous operating pressures, high tensile strength and low longitudinal elongation under pressure
  • completely embedded in polyurethane, thus optimal protection against mechanical damage

inner and outer layer:

  • thermoplastic polyether polyurethane, pressed through the textile insert in a special one-step extrusion process
  • highly abrasion resistant with service life of factor 4-5 compared to nitrile hoses
  • inside: very smooth for minimum pressure loss
  • outside: very smooth for good flexibility


  • stable in diameter
  • high tensile strength & layer adhesion
  • light & flexible handling
  • easy cleaning
  • space saving
  • extremly abrasion resistant


Working pressure:

Specifications apply only to the hose (medium water, 20°C). For hose assemblies with couplings, the possible operating pressure may be lower than specified above due to the nominal pressure of the couplings or the type of assembly. For compressed air, the maximum operating pressure is 25% of the burst pressure.

Maximum operating pressure:

Approval for this can only be given by the manufacturer after clarification of the exact area of application.

established since 1872

What began in 1872 with 1.5 km of hand-woven fire hose made of hemp by master rope maker Friedrich Gollmer is today the global player operating worldwide in various industries. Nevertheless, it is a family business - in the 5th generation.
