Application and limits

Application: Delivery hose for abrasive bulk materials in docks and on oil rigs.
Features: Highly abrasion resistant natural rubber inner tube, crossed copper wires for grounding, flame retardant cover, resistant to sea water, oils and ozone
Limits: Operating temperature from −40 to +70 °C.
Working pressure depends on the inner diameter — see the table. Burst pressure is a reference value, not a working pressure.
