Standard Seals

Seals can be manufactured to a specific geometry, but they can also be supplied in straight lengths.

Some straight-length profiles are flexible enough to follow non-linear installation paths.

Several aerospace standard families exist, including ASNA, ABS and NSA. Materials are commonly specified according to standards such as NFL17-250, ABR4-0080 or ABR9-0142.

Sealicone aerospace sealing solutions

Sealicone aerospace sealing solutions are designed to withstand demanding environmental and functional loads.

Resistance to environmental conditions

Seals may need to withstand extreme temperatures, exposure to fluids such as Skydrol, fuel and de-icing products, as well as sand, dust and biological contamination. Depending on the application, testing can be performed in accordance with procedures defined by standards such as RTCA DO-160, ABD0031, FAR 25.853 or MIL-STD-810.

Typical test standards

• RTCA DO-160
• ABD0031
• FAR 25.853
• MIL-STD-810

Resistance to mechanical loads

Sealing components must also withstand mechanical loads including abrasion, pressurization and significant deformation.

Standard seal families

Several standard seal families can be manufactured in straight lengths and formed during installation, including ASNA, ABS and NSA references.

Custom design and co-development

When a custom design is required, we work with your technical teams to develop a seal that meets the complete set of requirements while optimizing weight, aerodynamic performance, aircraft efficiency and safety.

Integration, maintenance and MRO

Sealicone seals are installed both during aircraft assembly by OEM equipment manufacturers and during maintenance, repair and overhaul operations by MRO teams.

Technical and quality support

Sealicone can manufacture components from your drawings under a build-to-print approach or develop sealing solutions from your technical specification under a build-to-spec approach.

Typical sealing applications

Seals are used at many interfaces throughout an aircraft. The following are examples of common applications:
