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.
DIN 14811 with STORZ couplings:
Ø 25–75 mm: max. working pressure 16 bar
Approval can only be given by the manufacturer upon clarification of the exact area of application.
