External covering in polyurethane, internal hose in polyester elastomer reinforced with 1 or 2 braids of aramid fiber plus one steel braid.
Burst pressure: 2800 bar
Maximum working pressure: 700 bar
Safety coefficient: 4
Internal diameter: 6,6 mm
External diameter: 13,7 mm
Minimum bending radius: 70 mm
Depending on their working conditions the hoses have limited life time.
Effective hose life time depends on:
– The effective working pressure
– The pressure peak
– The working atmosphere
– The working temperature
The hoses must be checked several times per year to detect leakages, collapsing, corrosion, wear or abrasion.
Hoses with external damage must be immediately replaced.
Replacement of hoses recommended at the latest every 10 years according to ISO NF EN 4413.
