Emco Wheaton G457, Helicopter Refuelling Nozzle
PLEASE EMAIL US FOR PRICING
EMCO Wheaton’s G457 is a nozzle designed specifically for helicopter refueling. This product was originally developed for a major NATO partner to support quick turnarounds in time-sensitive combat environments, particularly when hot refueling.
Features & Benefits
The G457 allows an operator to safely refuel a helicopter while its rotors are still running. Its innovative proximity lever eliminates the risk of fuel being sucked into the air intake, in turn removing the dangerous human error element encountered when hot refueling. The nozzle will automatically shut off when a helicopter’s tank is full, minimising spillages. It also features a manual override mechanism to allow an operator to fill a tank to its absolute maximum. This is especially important in situations where a helicopter needs to remain airborne for as long as possible.
