Typically used to prevent leakage of two joined pieces in waste tanks, potable water tanks, drain masts and fittings, gaskets are designed and manufactured to meet customer specifications.
O-Rings
 |
O-Rings are in fittings, valves, faucets, sensors, water heaters and water filters. They are available in EPDM, FKM, NBR, HNBR, and our proprietary FFKM, Isolast®, to supply water without leakage to lavatories and galley equipment. O-Rings can also be found in galleys and lavatories.
LSR Components
 |
Advanced injection-molding techniques, including micro-size, delicate part and thin section capabilities, produce high-precision LSR parts for faucets and water flow distribution. LSR Components can also be found in lavatories.
Hoses & Tubing
 |
Hoses and tubing for water distribution and drainage are available in a wide range of materials, including silicone and PTFE, and can be composed of multiple layers when the application requires chemical compatibility and high strength.
Bleed Air Systems
Diaphragms
|
We have extensive experience manufacturing elastomeric diaphragms both with and without fabric reinforcement. Inserts can be used to eliminate secondary operations. Diaphragms can also be found in engines.
Ducting Seals
|
Seals in the ducting guide hot bleed air from the aircraft’s engines or APU toward the anti-ice and ECS. Trelleborg’s Turcon® Variseal® solutions are available in standard geometries and as ‘trombone’ ducting. Ducting Seals can also be found in engines.
Hot Air Fire Seals
 |
Usually manufactured from fabric-reinforced silicone to accommodate movement in all directions and located between rigid ducts of various shapes, fire seals, including duct seals and kiss seals, require stringent fire testing. Hot Air Fire Seals can also be found in engines.
Plate Seals & Gaskets
 |
Gaskets and plate seals within the engine bleed air system reduce leakage, withstand elevated temperatures and high vibration. These seals typically consist of two components joined together, for example, in motors and gearboxes, ducts, manifolds, engines and auxiliary power units (APUs).
Routing & Clipping
|
To protect and guide bleed air, ducting incorporating thermoplastic components including P-Clamps and Band Clamps to prevent damage due to abrasion and vibration.
Bleed Air Systems
 |
Trelleborg manufactures seals for air valves for use within the bleed and cabin air stream. These high-quality products operate continuously at temperatures up to +260 °C /+500 °F. In ball, butterfly, regulating and high-pressure valves, they provide consistent low friction performance to meet opening and closing requirements.
Air Conditioning Systems
Composite Structures
|
Manufactured from resins and carrier materials, custom lightweight composite structures are suitable for use in plenums, ducts and resonators.
Air conditioning systems
|
Elastomer static seals, manufactured in a wide range of materials, including EPDM, FKM, NBR, HNBR and our proprietary FFKM, Isolast®, are suitable for HEPA filters, access door seals and valves. As well as offering a standard range of seals, we also design and manufacture custom components in non-standard shapes and sizes.
Turcon® Seals & Components
|
Operating in a wide range of temperatures and demonstrating high chemical resistance, Turcon® PTFE material is also non-toxic and has high fungal resistance, making it ideal for seals and components in the ACS. Turcon® is used in Variseal® sping-energized seals, Varilip® lip seals and custom designs, such as valve seats and diaphragms.
Turcon® Spring-Energized Seals
|
|
Suitable for use in hot air ducting and pipes, Turcon® spring-energized seals can operate in applications with temperatures up to +300°C / +572°F. These seals prevent air from escaping the bleed air ducts used, for example, in bleed valves, anti-icing systems and air conditioning systems. We can supply seals qualified to several Airbus ABS specifications. for use in plenums, ducts and resonators.
Cabin Pressurization Systems
Cabin Air Outlets
 |
Manufactured in lightweight materials, individual air outlets are compliant to fire testing requirements (including FAR 25.853) and offer easy and precise adjustment, to control the flow of ambient air.
