Take Off Into the Future

Aerospace is a trendsetter when it comes to innovation. Air traffic is becoming ever faster, safer and more efficient. The performance of the aircraft is increasing, at the same time the footprint of flying is to be reduced in the sense of sustainability. Airplanes therefore fly higher and higher in ever colder air layers; at the same time, their engines are operated at extremely high temperatures with environmentally friendly “lean” fuel mixtures. In addition, alternative fuels are gaining in importance on the road to sustainability towards carbon-free aviation, a long-term goal of the International Air Transport Association (IATA).

These trends are full of technical challenges and are tailor-made for a company that specializes in technology like Freudenberg Sealing Technologies. Whether with new materials, lightweight components, sophisticated designs or innovative technologies: with our global expertise in the aerospace industry, we have the right sealing solutions at hand. We thus give the entire industry a boost to take off into the future.

Product Range for Aerospace

Back-up Rings

Freudenberg Back-up Rings for the Aerospace industry support the sealing capability of O-rings by supporting against extrusion. Our Back-up Rings expand the operations conditions of O-rings while maintaining the flexibility to be used with a variety of seals. These retainers are available as solid elements, scarf cut, or as spiral rings. Back-up Rings are ideally suited to increase product life in high-pressure and extreme-temperature applications.

CapSeal

Omegat OMS-CS Cap Seals

Consisting of an engineered PTFE ring and an O-Ring as energizer in a two-piece rod seal set, Freudenberg’s Omegat OMS-CS Cap Seal is specifically designed for use in dynamic, reciprocating Aerospace applications when low friction is required. The special design of the anti blow-by notches assists a typical pressure peak within the O-ring at the rounded edge of the PTFE profile ring. These angled anti blow-by notches avoid additional sharp edges at this mostly stressed area of the O-ring. That means maximum protection of the O-Ring preventing premature failure.

Key Advantages

Fireproof

As a fire-resistant fire protection barrier, our sealing solutions withstand temperatures of 2,000 degrees Fahrenheit (1,093 degrees Celsius). This opens up a 15-minute window for fire-fighting and life-saving measures.

Aerodynamic

Freudenberg solutions not only reliably seal cabin doors, windows or hatches. With low-friction surfaces and lightweight materials, they also meet the goals of efficiency and sustainability.

Versatile

Thanks to Freudenberg’s unique range of materials, our O-rings are true all-rounders on board. Their temperature and chemical resistance benefits engines, wheels, brakes, control systems and hydraulic actuators.

Economical

Easy to assemble, cost-effective and multifunctional: Our application-specific optimized flat gaskets withstand extreme temperatures in engines and are used in fuel systems.

Resistant

Polytetrafluoroethylene (PTFE) is a low-friction special material that offers almost universal chemical resistance. PTFE seals for the aerospace industry are particularly durable and offer top performance in a wide temperature range.

Original

Original Simmerrings® from Freudenberg in metric and Anglo-American inch sizes are standard equipment on airplanes: in engines, transmissions, control systems, wheels and brakes.

Customized

Diaphragms developed and tested in-house for specific customers and applications are made of high-quality elastomer and polyurethane materials, tailor-made high- and/or low-temperature compounds and are available with fabric reinforcements.
