CINAR SILIKON · ISTANBUL, TURKEY
Inflatable seals and gaskets for your equipment.
Inflatable Gaskets presents Cinar Silikon's inflatable silicone sealing solutions. Compressed air expands the hollow profile to make contact with the mating surface; releasing the air lets the seal deflate so the equipment can open or move.

How it works
How Inflatable Seals
Work
The channel-fit silicone profile expands as air enters through the metal valve, conforming to the mating surface to create a continuous seal.
01
Deflated Position
Without air pressure, the profile rests compactly in its mounting channel, clear of the contact surface.
02
Air Supply
Air flows through the metal valve into the hollow chamber of the profile at a controlled pressure.
03
Full Contact
The profile inflates to meet the mating surface, creating a continuous sealing line.

Mounting solutions
Mounting Retainers
Three Installation Options
Three mechanical retainers that hold inflatable gasket profiles securely in place to suit the application.
01
Z-clip Retainer
Stainless steel Z-clips secure both sides of the profile to the base, allowing easy maintenance and replacement.
02
One-piece Slide-in Retainer
The profile slides lengthwise into a one-piece metal channel, providing continuous support and protection.
03
Split Two-piece Retainer
A two-piece metal channel grips the profile from both sides, simplifying installation and removal.

Frequently Asked Questions About Inflatable Seals
Find concise answers to common questions about profile selection, operation, mounting and air connections.
View All QuestionsAn inflatable silicone gasket expands against a mating surface when air is supplied at a controlled pressure. It returns to its original position when the air is released. Its operation is designed around the profile geometry and application conditions.
Inflatable gaskets can provide controlled sealing on doors, hatches, channels and moving surfaces in industrial applications. Suitability depends on the operating environment, surface geometry and process conditions considered together.
Profile selection considers the mounting channel, contact gap, direction of movement, surface geometry, operating environment and maintenance needs. Sharing a technical drawing or application photo helps identify the right profile.
Project-specific profiles, lengths, mounting arrangements and air connections can be developed after reviewing your dimensions and operating conditions. Manufacturing feasibility is confirmed following a technical review.
A technical drawing, channel dimensions, gasket section, overall length, operating environment, temperature, contact gap and application photos help us assess your enquiry. Our technical team can help establish any missing details.
