Areas of application
| Stability under pressure | |
| Flexibility at low temperatures | |
| Abrasion resistance |
In accordance with EN ISO 7751 specifications for water.
Please note that for compressed air a minimum ratio of 1:4 must be maintained between the working pressure and the burst pressure.
Pressure specifications apply only to hose lines with couplings extruded by us – otherwise only to the hose.
| Inside diameter in mm | Weight in g/m | Wall thickness in mm | Working pressure in bar | Burst pressure in bar |
|---|---|---|---|---|
| 38 | 500 | 4.0 | 60 | 120 |
| 52 | 700 | 4.0 | 60 | 120 |
| 65 | 960 | 4.8 | 60 | 120 |
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 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.
