At a glance


Material construction

Jacket lining:

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


Rubberized lining and jacket:

  • Very high-grade NBR/PVC rubber 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: Wide, thick ribs for maximum abrasion resistance and excellent protection against contact heat


  • Outstanding abrasion resistance, extremely tough and durable
  • Resistant to oil, gasoline and chemicals (see resistance table)
  • Extremely resistant to heat and flames
  • Very low pressure loss, minimum elongation
  • Resistant to aging and ozone
  • Excellent adhesion between the rubber and jacket
  • No cleaning or drying required


Pressure specifications apply only to the hose and not to pre-assembled hose lines with couplings!

150 years of

What began in 1872 with 1.5 kilometers of hemp fire hose a year hand-woven by master rope-maker Friedrich Gollmer is now a global player in many industries around the world. And yet it’s still a family business – now in its 5th generation.
