APS has an inventory of aviation sensing twin hose. This dual hose is suitable for hydrant pit valve connection to the cart or servicer. This hose is 3/8″ inside diameter nitrile (buna-n) tubes for fuel resistance.
The double-line Refueling Sensing hose is for use on pressurized aircraft hydrant fueling systems common at the larger metropolitan airports. The Sensing hose operates in a system where air and fuel from the underground hydrants monitor the flow and pressure of fuel being pumped into the aircraft. The hose carries the deadman function (automatic safety shutdown) and pressure control signals from the dispensing vehicle to the hydrant pit control valve.
