Single-run and multi-branch ducts in low-density polymer and engineered fabric, formed to almost any geometry. Where a joint would add a leak path, we build the seal into the duct instead. Designed and qualified in Retford, England, then made the same way for as long as your platform is in service.

By the time a duct is designed, the structure, systems and wiring around it already have their space. What is left is an envelope full of turns, clearances and fixings. A duct built from straight sections and stock bends can meet that envelope only one way: with joints.
Tight clearances around structure that was there first, and a route that changes direction more than once.
Every joint adds a clamp, a stress point and a leak path. Vibration works at it and pressure tests it, flight after flight.
Every clamp and bracket is weight the aircraft carries for the life of the platform.
A duct designed for one platform still has to be made the same way in year twenty.
Every duct is designed for one route on one platform. These are the forms that work usually takes.
ECS and air distribution runs formed to the route: lightweight, and leak-tight at low and high pressure.
Complete systems with branches stemming from a main duct, delivered as one assembly rather than a kit of joints.
Seals built into the duct where they remove a joint, cutting stress points and leak paths.
Inlet ducts that give the engine compressor a uniform supply of air, for jet engines and military vehicles.
304 and 316 stainless for sections that need strength and corrosion resistance in humid or high-temperature areas.
Round and rectangular sections fabricated to carry a run through spaces of different shapes.
We also supply the bellows, fasteners and connectors that join a duct to the rest of the system, so every interface comes from the same engineers as the duct.
Bellows & Expansion Joints →A duct can be assembled from straight sections and stock bends, joined wherever the route turns. Ours are formed instead, and that one difference changes the joints, the weight and the fit.
Our own low-density polymer formulations with engineered fabrics: light and flexible, for an industry where weight, durability, low maintenance and easy installation all count. Stainless steel where a section needs strength.
Our process forms a duct into almost any geometry, so it uses the space envelope instead of fighting it.
We build seals into the duct where they remove a joint. Fewer joints mean fewer stress points and leak paths, and better reliability in service.
Engineered-fabric plies are cut on CNC machinery, so every duct matches the last, order after order.
We 3D print intricate parts and prototypes, so the form is proven before production tooling is committed.

The same route, built two ways.

|---|---|
| Straight runs and catalogue bends, joined wherever the route turns. | Formed to the route, single run or multi-branch. |
| A clamp and a seal at every joint: weight, a stress point and a leak path. | Seals built into the duct where they remove a joint. |
| The design bends to the duct: an extra bracket, a rerouted harness. | The duct is designed to your envelope. Nothing else has to move. |
| Fit discovered at installation. | Fit proven before production. |
| A supplier for this order. | The same duct, to the same specification, for as long as the platform is in service. |

Our aircraft ducting is in service on commercial and defence aircraft, supplied to aerospace companies across the UK, mainland Europe and the USA. Each duct was designed for one platform and qualified to its standard, then made to the same specification on every repeat order.
Engineer to engineer, from the envelope you send to the duct on your platform.
A CAD model of the space, the route, the interfaces at each end, and the pressures, temperatures and flow. A drawing helps; a described problem is enough. An Icon engineer comes back to you within two working days.
Route, materials and construction designed engineer to engineer, with seals built in where they remove a joint. Prototypes prove the fit, then testing, qualification and first article inspection to AS9102.
Approved ducts move into production in Retford, made to the same specification with full traceability, for as long as the platform is in service.

Single-run and multi-branch flexible ducts, including ECS and air distribution ducting, ducts with integrated seals, engine inlet ducts and S-ducts, 304 and 316 stainless steel sections, and fabricated round, rectangular and transition sections. Every duct is designed for one route on one platform.
Yes. That is the point of forming a duct rather than assembling one. Our process can form almost any geometry, so send the envelope as a CAD model or drawing and we will design the route to it.
An integrated seal is formed as part of the duct instead of being fitted at a joint afterwards. Removing the joint removes a clamp, a stress point and a leak path, so the duct is lighter and more reliable in service.
It depends on the section. Flexible polymer and fabric ducting is lighter and routes through tighter envelopes. Stainless steel suits sections that need strength and corrosion resistance in humid or high-temperature areas, and we supply both.
An engine inlet duct feeds air to the engine; an S-duct is an inlet duct with an S-shaped bend, used where the air has to route around structure. Both exist to give the compressor a uniform supply of air so it does not stall.
In three ways. We form ducts to the route instead of assembling them from straight sections and stock bends. We build seals into the duct where they remove a joint, so there are fewer clamps, stress points and leak paths. And we design, qualify and make every duct on one site in Retford, England, where your enquiry goes to an Icon engineer, not a remote sales hub.
Yes. We manufacture to print with first article inspection to AS9102. If we see a change that would remove a joint or save weight, we will tell you before we quote.
The envelope (CAD model or drawing), the interfaces at each end, operating pressure and temperature, the media and flow, any fire requirement, the specification you have to meet, and expected volumes.
