Aviation Refuelling Nozzles

Aviation Refuelling Nozzles

EWFM supply a range of aviation refuelling nozzles.  Our range includes the G457 Hot refuelling Nozzles and standard G180 refuelling Nozzles.  Both nozzles come in a range of variations dependant on customer requirements.  These Nozzles are supplied to ensure safe refuelling, minimising the risk of damage to the aircraft and the operator.


Refuelling Nozzle – Model G180

EWFM supply the ALL NEW G180 series over-wing refuelling nozzle that has replaced the G457-240 series nozzle which has been in use with the United Kingdom MOD for many years. As a result of listening to the operators in the field and UK MOD engineers it now incorporates many new features and benefits. This refuelling nozzle is designed to be lightweight and comfortable to operate.

A Speed Spout system has been designed to give the operator the choice of which spout suits the aircraft. As a result it allows the spouts to be changed in a matter of seconds.

Spout configurations

  • Flared
  • 1.5″ straight
  • 1″ straight
  • With or without a bumper ring

Features & Benefits

  • Soft Close – This permits the operator to control the flow of fuel.
  • Bumpers – If the operator places the nozzle on the wing the contact rubber bumpers protect the wing material.
  • Designed for wearing heavy gloves. This allows the operator to wear protective clothing especially in cold weather.
  • Anti-FOD component design. The components are fitted with anti FOD designed parts
  • Light weight construction. The nozzle with 1.5″ spout, inlet check valve and the optional bumper ring weighs 3.15 kilos (6.95 lbs)
  • Ball bearing inlet swivel. This allows some rotation and facilitates refuelling.
  • Soft Dust Cap & lanyard. This is easy to fit and protects the spout.
  • Quick coupling Speed Spout design is easy to use and fast to change.


Hot Refuelling Nozzle – Model G457

The G457 hot refuelling nozzle has been in operation with the United Kingdom MOD since the 1970’s. The requirement for Hot Refuelling was identified as an essential safety feature permitting the aircraft to be refuelled with the turbines and avionics running. These aviation refuelling nozzles allow for rapid turn round of the aircraft, safely reducing the risk of injury to the crew and damage to the aircraft. In addition the nozzle is used in all climates and furthermore the hot refuelling nozzle is also available with a special extra low temperature design. As a result this tried and tested design has built up an excellent reputation for safety and reliability.


  • Construction material Anodised Aluminium
  • Proximity lever.
  • Automatic high level shut-off
  • Froth dissipater sleeve
  • Manual override button
  • Flow control mechanism
  • Inlet strainer: 100 mesh
  • Dust Cap
  • Grounding Wire assembly with Jack Plug and Crocodile Clip
  • Curved or straight spout option
  • Temperature Range: -30ºC to +52ºC
  • Low temperature design available on request


  • The material of body construction is resistant to fuels and vapours ensuring a corrosion free long life.
  • Fuel will only be delivered when the lever is depressed against the fuselage to prevent spillage
  • High level shut off therefore protecting the operator and aircraft from spillage when the tanks are full.
  • Froth dissipator allows maximum fuel flow without the shut off operating prematurely.
  • Manual override button is also a safety feature consequently protecting crew and aircraft.
  • Flow control mechanism ensures a regulated and steady fuel flow.
  • Inlet strainer stops foreign particles entering the fuel tanks
  • Dust cap keeps the spout clear of particles in addition to the strainer.
  • Grounding wire and crocodile earths the aircraft consequently preventing build up of static.
  • Spouts van be curved or straight depending on the design of the fuel inlet.
  • Lastly the nozzles can be used from hot deserts to Arctic regions.

Floating Suction Units

Floating Suction Units

EWFMs Floating Suction Units are the most popular products in our storage tank equipment range.  We can supply the Double Arm Floating Suction Unit and Single Arm Floating Suction Unit.  We also, for a different process, supply the Articulated Roof Drain.


What’s the difference between floating suction units and articulated roof drains?
  • Floating suction units are used in aviation fuel or oil storage tanks and are designed to draw fuel from just under the fuel surface. This fuel is the purest and isn’t contaminated by sediment that sits on the fuel surface nor the water that congregates at the bottom.
  • The articulated roof drain is designed specifically for the removal of rainwater and snow melt from the top of storage tanks with a floating roof.


Why a double arm?

The double arm floating suction unit is designed for tanks where the height is greater than the diameter.  There is usually a leg set according to the tank size to stop the floating suction assembly drawing fuel off near the bottom of the tank where it may be contaminated by water. Consequently this gives a longer life to the water separator cartridges and an increase in their efficiency.


Extra Information
  • Floating suction assemblies are made in aluminium as standard but stainless steel versions are available. Internal diameter sizes range from 1” to 12” as standard, but larger sizes up to 48” can be supplied.
  • The articulated roof drain, supplied with a Style 40 Rotary Swivel Joint, is available in stainless steel or carbon steel. Sizes available are 3”, 4”, 6” and 8”.
  • The tanks can be above or below ground, can be horizontal or vertical and have either a floating or a fixed roof.
  • Did you know floating suction units are mandatory at aircraft refuelling facilities?

  • 8”

Our top loading arms can also be supplied with numerous optional extras, some of these include:


Bottom Loading Arms

Bottom loading arms are generally fitted with an API or dry break coupler that connects to the mating adaptor on the road or rail tanker.  Like our top loading arms, bottom loading arms also come in a wide range of configurations.  Very often they are supplied staggered (like in the picture above).  This allows the arms to overlap and fill multiple compartments at the same time.  These arms are very often distinguished with colour coded hose covers.

Our Bottom loading arms can also be manufactured in:

  • Aluminium
  • Carbon Steel
  • Stainless Steel
  • Alternative materials on request

In sizes of:

  • 1”

Loading arm couplings

Loading Arm Couplings

Loading arm couplings are used to ensure a safe, dry and quick connection to that of a mating road or rail tanker. The most common range used for hydrocarbon loading arms is the API Liquid Coupler and the API Vapour Coupler.  We also however offer the full range of Mann-tek Couplings (according to STANAG 3756) which can also be used dependant on your mating connection.


API Liquid Coupler – Aluminium

The 4″ Female API Couplers (Liquid) Model C-2659 are for bottom loading hydrocarbon road tankers.

This is an industry standard design according to the American Petroleum RP1004 and consists of 7 operating lugs, 5 interlock lugs and 2 trigger mechanisms for security.   We also offer a bio-fuel version on request.

In addition we use the female API coupler as standard on our Bottom Loading Arm models 740, 750 and many others.


API Vapour Coupler – Aluminium

Designed for road tanker bottom loading, the 4” API Vapour Coupler connects to the tank trucks mating male vapour adaptor.  It has been designed for use with Loading Arms and flexible hose assemblies, for use with hydrocarbon products.

This API vapour coupler also has a TTMA flange with a check valve that ensures it is sealed when it is not connected to a tank truck. Furthermore the locking system between the two parts is a Cam and Groove type and is engaged by the two levers on the side of the coupling.  Once again this coupling is made in accordance with API RP1004


Mann-tek Couplings


The Dry Disconnect Coupling, can be used for connection and disconnection of Loading arms to and from tankers.  They work on the “push and turn to connect” system, and when coupled you have full flow.  Similarly to disconnect, “turn and pull” and then it is released with no spillage.  Dry Disconnect Couplings are our standard choice for handling liquids and are available in sizes from ½” to 8” in materials including Stainless Steel, Aluminium, Brass and Hastelloy.  If you are unsure, please give us a call and we will help to advise the correct product for you.


In many cases where extra safety is required we also equip safety breakaways to our loading arm couplings.  In the event a tanker moves off while a coupling is still connected the safety breakaway removes the risk of damage and safely breaks cutting off the fluid.



Drilling Swivels

At EWFM we supply Drilling Swivels as part of our wide range of Rotary Unions. Whether you are drilling for oil, water or gas these swivel are designed to allow rotation of the drill while conveying high volumes of high pressure drilling mud.  These swivels are also used for horizontal drilling.


Being a specialised industry Drilling needs special swivels to do a hard job.  Usually they are available in 3” and 4” and are made of hardened carbon steel for durability. Very often this application requires special flanges and they are made to suit your mating connection.


Due to the harsh environment in which these swivels operate, the seals will be prone to deterioration and will corrode.  At EWFM we can provide replacement seal kits which will prolong the life of the swivel joint, making it more cost effective for our customers.


The many countries we have supplied drilling swivels to include Australia, Chile, China, India, Poland, UAE and the USA.


At EWFM we have a long history in supplying Swivel Joints to the oil, gas and subsea industries, and also the chemical, pharmaceutical, food, distilling, brewing and petrochemical sectors.


Not only do we supply standard swivel joints we also supply engineered, subsea swivels, compact swivels, high pressure swivel joints, and multiport rotary unions.  Most of our swivel joints can be supplied in a range of styles and sizes.


Forming an integral part of articulated pipework assemblies such as loading arms and floating suctions, swivel joints also relieves stress and torsion on hose or pipework.  This prevents damage which could result in costly downtime through repair and delays.


The best way to check if we can supply your requirement, is to contact Guy or Mike at  or call them on +44 1763 248650 and they will be happy to discuss your need with you
