Bespoke seals, hoses, ducting and running gear for aerospace, defence and industrial platforms

Complex requirements. Engineered together.

When the part your platform needs does not exist in any catalogue, our engineers sit down with yours — and design, qualify and manufacture it in Retford, then keep making it for as long as your platform is in service.

The problems we solve

The part that almost fits.

Most polymer components are chosen from a catalogue. On a certified platform, "almost fits" is a risk: a failed fire test, a leak path at altitude, a late delivery that stops a build line, a supplier that exits with twenty years of service life still to run.

Where the almost-fits part gives up

ICON
At the fire test.

The sector expects up to three attempts per seal. Each failure is weeks of repeat testing while the engine programme waits.

ICON
At altitude.

A leak path, a weight penalty, or an in-service issue that surfaces on the aircraft instead of on the rig.

ICON
On the build line.

A late hose or duct stops a build as surely as a late engine — for a part that cost a fraction of anything around it.

ICON
In year fifteen.

A supplier exits or a compound is withdrawn. The part is obsolete, and the platform needs a redesign and a full requalification.

Small on the bill of materials. Enormous on the risk register. Discovered at qualification, it is a repeat test measured in weeks. Discovered in service, it is a redesign, a requalification, and a name on the programme review.

There is nothing on this site you can buy from a shelf. That is the point.

How we engineer it instead ↓

Products & solutions

Yes, we make hoses, seals and mouldings.

Each one is the output of an engineering programme: designed for one place on one platform, qualified to its standard, and manufactured for as long as that platform flies, drives or runs.

The engineering difference

Talk to the people who will make your part.

We know a seal is a fraction of your bill of materials — and all of your risk if it fails a fire test. We know what it is to explain a requirement, twice, to a sales office that has never seen a drawing.

So there is no sales office between you and our factory. Icon Aerospace Technology has engineered bespoke polymer components — aerospace seals, hoses, ducting, mouldings and running gear — on the same site in Retford for more than 150 years. Your enquiry goes to an engineer. Your design review happens with the people who will make the part. And when you want to see the rigs, the tooling and the shop floor, you are welcome to.

We call it face2face engineering. Complex requirements, engineered together.

The face2face Engineering Process

From gap to qualified part, in three steps.

Three steps, named so you can repeat them — and what you have in hand at the end of each one.

IMAGE — Icon engineer and customer at the table, specification and drawing between them · new shoot
Step 1 · Meet

Bring us the gap.

Send the specification, the envelope and the environment — or simply describe the problem. An Icon engineer responds within two working days with a first view on feasibility, materials and what it will take. In Retford, at your site, or on a call.

You getA real answer from someone who will make the part.

Step 2 · Engineer

Design and qualify it together.

Design and FEA. Compound selection or development. 3D-printed tooling and samples in days, not months. Fire, thermal, pressure and environmental testing on rigs built to replicate your service conditions, then formal qualification and first-article inspection to AS9102.

You getA part designed for one place on one platform, with the test evidence to prove it.
→
IMAGE — Production floor, post-2020 equipment, parts on the line with traceability labels · new shoot
Step 3 · Perform

On time, on quality, for the life of the platform.

Industrialised production and repeat supply for as long as the platform is in service — with full traceability, planned obsolescence, and an engineer who still picks up the phone in year twenty.

You getThe part keeps arriving. It comes off your risk register.

Platform proof · one point, told fully

The industry budgets three attempts per fire test. We have never needed two.

100%first-time pass rate — all eleven fire-seal qualification tests · sector norm: up to three attempts per seal

Programme. Fire testing is where qualification programmes stall — the sector plans for repeat attempts on every seal. Over an eight-year programme, we developed a formulation and construction that passed every one of its eleven qualification tests first time — at more than 1,093 °C, under vibration, airflow and pressure differentials, on rigs we designed ourselves.

In service. Those seals now protect engines, APUs and fuel systems in service today.

Why engage ICON early

The best time to involve us is before the drawing exists.

Every decision made without the material in the room gets more expensive downstream: at qualification it is a repeat test measured in weeks; in service it is a redesign, a requalification, and a name on the programme review.

Bring us the gap at the design stage and you get a straight answer on feasibility, materials, lead time and cost before you commit — and a part that passes qualification first time, on a rig built to replicate its service conditions, then ships batch after batch for decades.

Engage early and here is what you can expect — six commitments, each with an owner and a measure.

1
You will always be able to speak to the engineer working on your part.

No central sales office, no ticket queue.

2
We design and qualify to your specification.

We never adapt a catalogue part and call it bespoke.

3
We tell you what is feasible — and what is not — before you commit.

A straight answer on lead time and cost is part of the service.

4
We deliver on time and on quality, every time.

Supported by a published on-time-delivery figure, reviewed annually.

5
We support the part for as long as your platform is in service.

Obsolescence is planned, not discovered.

6
We protect your drawings, data and intellectual property.

Non-disclosure agreements on request. Export-control and data-handling wording exactly as quality and legal approve it.

We are rarely the cheapest quote. We are usually the last one you will need.
