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.
In accordance with BS 6391:2009:
Ø 38–89: 22.5 bar
