Inflatable seals

Static or dynamic sealing solutions: an inflatable seal comes to compensate for a difference in pressure and/or temperature variations between an indoor environment and its external environment.

Our job: to ensure perfect sealing

Sealing solutions fill spaces, to create a barrier between deltas of pressure and/or large temperature variations between an enclosure and its environment.

Pneumatic jack rule development between two movable components maintaining a constant pressure, mastered and non-traumatic.

sterne-silicone-rubber.comThe mainspring

Hollow profiles, stretched out of shape by bringing pressure in (air, gas, fluid,…), vulcanized into a ring, frame, or straight length sealed at both ends.

Pressure is applied through a valve that is either over molded with a cone, or mechanically added. Rigid and/or flexible connections are also manufactured.

Our materials

We offer and transform different kinds of silicone rubber, mainly available in two consistencies:
High Consistency Silicone Rubber (HCR) and Liquid Silicone Rubber (LSR).
Two catalysts are predominant in the silicone industry: peroxide and platinum.

Diodon™ : A range of high performance silicone essentially used as a complement to the Hightube™ range. End to end connections and soldering are realized by injection.

Our applications

Optimum sealing in the fields of: food and drink, medical / biomedical, pharmaceutical / cosmetic industry, nuclear, mass transit: aeronautic and railway.

Various applications such as: powder and fluid cans, loose goods, transport and logistic (containers,...), lock chamber sealing, isothermal chambers, doors, etc

Warranties & certificates


We perform a range of tests specifically dedicated to inflatable seals for serial testing of performance under pressure.

For each unit set processes that depend on specific uses are automatically created, registered and archived.
