Areas of application
| Abrasion resistance | |
| Bending radius | |
| Stability under pressure |
Specifications apply only to the hose (medium water, 20 °C). 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.
BS 6391:2009 with British Instantaneous couplings:
Ø 38–76 mm: max. working pressure 15 bar Ø 89: max. working pressure 12 bar
Approval can only be given by the manufacturer upon clarification of the exact area of application.

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.
