Air hose incorporated in pneumatic closed-circuit control systems associated with aircraft fueling operations

Deadman Twin Sensing Hose Red / Green

Series 7139 is a flexible air hose incorporated in pneumatic closed-circuit control systems to prevent fuel spills during aircraft fueling operations. The hose is connected to air-actuated shut-off valves that are controlled by the aircraft fueling operator at all times during fueling operations. Series 7139 hose lines are chemically bonded to prevent separation and maximize flexibility, and the distinctive red/green covers provide color-coded identification. The hose features a nitrile tube that is resistant to oil and a chloroprene cover that is resistant to oil and weathering.
