Quality seals
Sagaert'saerospace division is certified in accordance with the EN 9100 standard.
With 15 years of experience, we design, manufacture, and qualify seals for environments with the most severe conditions, using the specifications and environmental conditions to define the geometry and components.
Our Seals in Detail
Where are our seals installed?
Our seals are installed on the radomes, landing gear, doors, wings (slats, flaps, ailerons, spoilers, fairings, engine masts, winglets), jet engines, access hatches, and tail section.
What materials do you use?
We offer a wide range of materials to precisely meet your requirements: silicone, chloroprene, nitrile, and fluorosilicone for elastomers; and polyester, Nomex, glass, Kevlar, and carbon for reinforcements.
What sizes of gaskets can you manufacture?
Our modern, high-performance production facilities enable us to manufacture seals ranging from a few centimeters to several meters in length, from O-rings to straight sections and door seals.
Do you offer a rapid prototyping service?
Yes. To meet our customers’ need for responsiveness, we design and machine our own manufacturing tooling, which allows us to produce parts in the shortest possible time. For the most urgent needs, or to validate a feature on a test bench or prototype, we have developed a rapid prototyping manufacturing process.

Aviation Seals: Frequently Asked Questions
Is Sagaert certified for the aerospace industry?
Yes, Sagaert's aerospace division is certified to the EN 9100 standard—the benchmark quality standard for the aerospace industry—and has 15 years of experience in the design and manufacture of seals.
On which parts of an aircraft are your seals installed?
Our seals are used in radomes, landing gear, doors, wings (slats, flaps, ailerons, spoilers, fairings, engine pylons, winglets), jet engines, access hatches, and the tail section.
What elastomer materials and reinforcements do you offer?
For elastomers: silicone, chloroprene, nitrile, and fluorosilicone. For reinforcements: polyester, Nomex, glass, Kevlar, and carbon. The choice depends on the part's specifications and operating environment.
What is the maximum size of an aerospace seal manufactured by Sagaert?
From a few centimeters (O-ring) to several meters (straight sections or door seals), depending on the project's requirements.
Do you manufacture your own production tools?
Yes, Sagaert designs and manufactures its own tooling in-house, which reduces production lead times. A rapid prototyping process is also available for urgent needs or to validate a feature on a test bench or mock-up.
What tests and quality checks do you perform on the seals?
Our seals are tested on fatigue cycling, pressure resistance, and water tightness test benches, and are designed using Catia V5.
