EMCO Wheaton’s aviation equipment sets the standard for fuel transfer and aircraft refueling in the toughest environments. Our helicopter and overwing nozzles and couplings are proven to take the strain in tough environments, having been used by both commercial and military operators throughout the world.

The G457 Helicopter Refueling Nozzle was originally developed by EMCO Wheaton for military applications, but is now used across the entire aviation market. Its design ensures fuel cannot be accidentally delivered into the engine air intake during hot refueling. Commercial helicopter operators will appreciate the significant cost advantages, not least the reduction in turbine cold starts.

The G180 Nozzle is based on a modified G457 chassis. The G457 has been the preferred nozzle of many military organizations around the world for many years. In opting for the G180, you will benefit from the experience we have gained in the field with this proven design. This product also comes with an optional speed spout, which gives operators the option to change fittings in less than five seconds. Ideal for time-sensitive operations where a high turnover of aircraft refueling is needed.

EMCO Wheaton’s sister company, TODO, also offers a wide range of premium products for refueling aircraft in the toughest conditions. These include the TODO-45 and TODO-MATIC dry-break couplers. You can find out more about these products by clicking on the links below.
