Emile Janique

Custom leather seals and bellows
for aeronautics

In aeronautics, every component must be reliable, traceable and manufactured with precision. A seal that fails on assembly line tooling or an incorrectly sized bellow on maintenance equipment means production stoppages that this sector cannot tolerate. We have been manufacturing leather seals, bellows, sleeves and protection covers for aeronautics for many years. Clients such as Eurocopter trust us because our parts are documented, traceable and manufactured in accordance with our ISO 9001 certification

We manufacture everything in our workshop in Reyrieux, in the Ain, without subcontracting. Each part is designed by our design office and manufactured by our team. Single unit for a prototype or small series for a production line, we handle both.

Emile Janique products
used in aeronautics

Each product we manufacture can be used on your aeronautical equipment according to your application and technical constraints.

Dynamic leather seals

For your assembly line tooling and maintenance equipment, on positioning cylinders and displacement shafts. Leather offers flexibility and friction resistance that synthetic materials do not always replicate on these applications.

Cut seals

For the static sealing of your flanges, housings and connections on aeronautical manufacturing tooling. Available in leather, NBR, EPDM, FKM or PTFE elastomers according to your technical requirements.

Moulded protective bellows

For your cylinder rods, displacement shafts and guides on aeronautical manufacturing and maintenance equipment. Available in leather, PVC, silicone-coated Kevlar or PTFE according to your environmental constraints.

Leather and silicone sleeves

For your ventilation and air circulation ducts on your assembly equipment. We manufacture them custom-made from your exact dimensions.

Leather and PVC protection covers

For your control panels, hoods and sensitive equipment on aeronautical production lines. Manufactured custom-made according to your equipment dimensions.

Traceable and ISO 9001 certified parts for your aeronautical requirements

In aeronautics, traceability is not optional. Every part we deliver to you is documented and traceable in accordance with our ISO 9001 certification. We are also the only European company certified ISO 9001 and ISO 14001 for the production of leather seals and bellows. We hold the Entreprise du Patrimoine Vivant label. You know exactly what you receive and how it was manufactured.

    FAQ: leather seals and bellows
    for aeronautics

    Are your parts traceable and compliant with aeronautical requirements?

    Yes. Every part is documented and traceable in accordance with our ISO 9001 certification. We provide the traceability elements required for your manufacturing file.

    Yes. We manufacture both single units and series production. No minimum quantity imposed. That is one of the advantages of leather: no costly specific tooling for custom manufacturing.

    We work with leather, PVC, silicone-coated Kevlar, PTFE and NBR, EPDM and FKM elastomers according to your technical constraints and working environment.
