Sealing solutions
Aircraft seals are highly complex and subject to stringent safety and design criteria. Our engineering expertise has been used to create over 10,000 designs. Over 7000 of these are in series production.
Aircraft seals are highly complex and subject to stringent safety and design criteria. Our engineering expertise has been used to create over 10,000 designs. Over 7000 of these are in series production.
We seal essential spaces, such as landing gear, wings, engines, nacelles, windows and doors. Our products are highly flexible, yet rigid enough to maintain structural integrity.
We separate essential spaces. Our products stop fire spreading between engine zones, ensure bleed air does not bleed and hydraulics do not leak. This minimises component contamination and optimises system performance.

Airlines are constantly striving to improve noise and fuel efficiency.
Any gaps on the aircraft change the air flow from laminar to turbulent, creating noise and drag and requiring more fuel to propel the aircraft through the air.
Our seals are designed to minimise both.
Our aerodynamic seal designs reduce parasitic drag, optimising performance at cruise condition and avoiding clashes with moving parts.
We seal:
Some key design features include:
Our engine seals stop fires spreading between engine zones. They have to prevent a flame from penetrating the protected compartment or section for 15 minutes – or be fire-resistant (five minutes).
The seals also have to self-extinguish if they catch alight themselves.
We seal the following engine areas:
We provide door seals for:
The design of an aircraft door is geometrically complex therefore door seals can be highly bespoke products. It must be completely airtight to prevent water ingress. It must also be easy to open.
Some key design features include:
As more composites are used in aircraft design extra care has to be taken with the loads that are placed on them – if the loads are too high, the composite panels are in danger of cracking.
Rubber – the primary material for seals – is a non-linear material. Unlike metal (a linear material which behaves consistently when a load is applied), rubber does not behave in an entirely predictable manner.
Our seals are designed to be flexible and strong.
These seals are made in our factories in Loughborough (UK), Oregon (USA) and Xiamen (China).
