Application and limits

Application: Suction and delivery hose for aircraft ground refuelling; fuels with up to 50 % aromatics.
Features: Flame resistant cover, two crossed copper wires for grounding, conductive inner tube
Limits: Operating temperature from −30 to +70 °C.
Working pressure depends on the inner diameter — see the table. Burst pressure is a reference value, not a working pressure.
