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

Specifications apply only to the hose. The potential working pressure may be lower than specified above for hose lines with couplings due to the nominal pressure of the couplings or the type of assembly.
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.
