Application and limits

Application: Delivery hose for aircraft ground refuelling; fuels with up to 50 % aromatics. Conductive inner tube and cover.
Features: Flame resistant cover, 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.
Also available with two copper bonding wires, and as a low temperature version down to −50 °C.
