Aerospace Sealing Solutions

We provide high-performance sealing solutions that meet the stringent demands of the aerospace industry. Whether for commercial or military aircraft, our seals ensure durability, efficiency, and safety across various systems.

Engines and Fuel Systems	Jet engines - seals to prevent fuel leaks, oil contamination, and ensure efficiency. Fuel tanks, fuel lines, and fuel pumps - prevent leaks and maintain system performance.
Landing Gear Systems	Landing gear actuators, shock absorbers, and brakes - prevent contamination from dirt, water, and other elements. Seals for hydraulic systems for landing gear operation to ensure proper function and leak prevention.
Hydraulic and Pneumatic Systems	Hydraulic actuators, valves, and cylinders - maintain fluid pressure and prevent leaks in control systems. Pneumatic systems - seals ensure proper functioning of flight control systems and environmental control systems.
Environmental Control Systems (ECS)	Proper sealing of air conditioning, pressurisation, and ventilation systems maintains internal air quality and pressure. Air ducts, valves, and compressors - prevent air leaks and optimise system performance.
Avionics and Electrical Systems	Avionics components, sensors, and connectors - protect against dust, moisture, and electromagnetic interference (EMI). Circuit boards, enclosures, and connectors - ensure durability and reliability.
Control Surfaces and Flight Systems	E.g. flaps, rudders, and ailerons – prevent air leaks and enhance aerodynamic performance. Actuators and control cables - seals ensure precise movement and resistance to external elements.
Missile and Spacecraft Systems	Missile systems, spacecraft, and satellites - protect sensitive components from harsh environmental conditions. Pressure vessels and systems - maintain vacuum integrity in space applications.

Custom Engineered Seals for Aerospace & Defence

One of our specialisms is creating custom sealing solutions to meet specific challenges, where standard seals are not suitable. Calling upon our many years of experience, our technical team can work with customers to develop new seals and gaskets that precisely fit their application needs. With in-house design and manufacture, we can design and produce the most complex sealing solutions for the most challenging industries. Our facility is equipped with advanced CNC machinery, and we have over 240 different engineered material grades in stock for a quick turnaround.

Materials

To guarantee optimal sealing performance, we offer a comprehensive range of sealing materials with industry-leading properties. We can recommend the best option to meet the specific environmental and operational needs of your project, ensuring peak performance, safety, and longevity.

Sealing materials include:

Fluorosilicone (FVMQ): Excellent resistance to fuel, oils, and solvents, making it an ideal material for sealing in aerospace fuel systems and defence fuel storage applications.
FKM (Viton^TM): Known for its high-temperature resistance, chemical compatibility, and low permeability, FKM is commonly used in fuel systems, hydraulics, and high-pressure environments.
PTFE: Non-reactive and temperature resistant, PTFE seals are perfect for applications exposed to corrosive environments or extreme temperatures.
Nitrile (NBR): Offering strong resistance to oil and fuel, NBR is widely used in aerospace hydraulic seals and defence equipment that requires flexibility, strength, and chemical resistance.
EPDM: Ideal for sealing applications in both aerospace and defence that demand durability and resistance to ozone, weathering, and ultraviolet exposure.

Quality & Industry Standards

Our Quality Management System is fully compliant with EN 9120:2018, enabling us to reliably supply products to the aerospace, offshore, defence, and critical application sectors.
