Bespoke seals, hoses, ducting and mouldings 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

Complex requirements rarely fit standard components.

Most polymer components are chosen from a catalogue. On a certified platform, a part that 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 a standard 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A supplier exits or a compound is withdrawn. The part is obsolete, and the platform needs a redesign and a full requalification.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

Engineered around the application.

When standard components cannot meet the full requirement. Each product is the output of an engineering programme: designed for one place on one platform, qualified to its standard, and made for as long as that platform flies, drives or runs.

IMAGE — Multi-branch flexible aircraft ducting

Flexible Ducting

Air distribution and environmental-control ducting formed to almost any geometry, single run or multi-branch, with seals built into the duct where it removes joints and leak paths.

Airframe & Aerodynamic Seals

Wing fillet, pylon, fairing and access seals, plus engine and pylon fire seals approved to AC 20-135 — fabric-reinforced silicone, fluorosilicone or neoprene, with inserts where the seal carries load.

How we engineer

Your engineers and ours, in the same room.

We know a seal is a fraction of your bill of materials — and all of your risk if it fails a fire test. So there is no remote sales hub between you and our factory. 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 in Retford, you are welcome to.

Face to face with the engineers who design, qualify and make your part — from the first conversation to the life of the platform.

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, parts on the line with traceability labels
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, obsolescence planned rather than discovered, and an engineer who still picks up the phone in year twenty.

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

IMAGE — Fire-seal test rig mid-test, flame on the seal face
Tested where it matters most

Fire testing is notoriously hard to pass. Ours passed first time.

Across the industry a seal can need up to three attempts to comply. When we developed engine fire seals for a major aero-engine OEM, every seal passed at the first attempt — each holding a 1,093°C flame for 15 minutes under vibration, airflow and pressure differentials, on rigs we designed ourselves.

Why engage Icon early

The earlier we see the gap, the more of the platform we can protect.

Weight, joints, qualification risk and twenty years of supply are all decided at the design stage. Bring us in then, and the polymer components become the one thing nobody mentions in the programme review.

IMAGE — Part on the platform: line illustration of where it sits

Engineered for the application. Made for the life of it.

Designed to your envelope, environment and standard, then made to the same specification for as long as the platform is in service. Obsolescence planned, not discovered.

IMAGE — In-house test rig and compound lab

Qualified right, first time.

In-house compounds, in-house rigs, first-article inspection to AS9102. The schedule stays protected and your name stays safe on the specification.

IMAGE — Design review with the customer, shop floor in the background

Face to face with the engineers who make your part.

Design reviews with the people on the shop floor, in Retford or at your site. Straight answers on feasibility, lead time and cost before you commit.

See it for yourself. Customers who visit tend to decide on the shop floor. Come and see the rigs, the tooling and the people who would make your part — in Retford, England.
