Inflatable Seals

Advanced Pneumatic Sealing Solutions

Inflatable Seals are specially engineered elastomeric sealing components that expand when pressurized with air or another suitable medium, creating a secure and adjustable barrier between two mating surfaces.

Unlike conventional compression seals, inflatable seals can accommodate variable gaps, uneven surfaces and movement between components. When inflated, the seal expands to achieve reliable contact; when deflated, it retracts to allow easy opening, movement or removal of the mating component.

They are available in a wide range of profiles, sizes, elastomer compounds and configurations, including custom-designed solutions for demanding industrial applications.

Important: Pressure, temperature, working height, stroke, dimensions and cycle life must be confirmed against the final seal design and operating conditions. Reinforced inflatable seals can be engineered for substantially higher pressure and demanding environments.

Recommended for: Water, steam, outdoor environments and weather-exposed applications.

EPDM provides excellent resistance to weathering, ozone, water and steam, making it a versatile choice for general industrial sealing applications.

  • Pharmaceutical & Medical

    Inflatable seals are used in equipment where controlled environments, hygienic sealing and reliable access are required, including pharmaceutical processing equipment, cleanrooms and medical systems.

    Food Processing

    Silicone and other approved compounds can be selected for food-processing equipment where hygienic sealing and resistance to cleaning processes are important.

    Aerospace & Defence

    Inflatable sealing technology is used for aircraft doors, hatches and canopy applications where reliable pressure-tight sealing and controlled opening/closing are required.

    Marine & Offshore

    Inflatable seals can provide watertight barriers for doors, hatches, panels and offshore equipment, including applications exposed to seawater and demanding environmental conditions.

    Automotive

    Used in vehicle doors, windows, sunroofs, testing equipment and specialized automotive machinery where adaptable sealing is required.

    Chemical & Process Industries

    FKM, EPDM, Nitrile and other specialized compounds can be selected according to chemical exposure, temperature and pressure requirements.

    Industrial Machinery

    Suitable for machine doors, chambers, covers, enclosures, inspection systems and equipment requiring frequent opening and closing.

    Transportation & Loading Systems

    Inflatable seals can be used around loading docks, vehicle interfaces and industrial doors to reduce air, dust and temperature leakage.

    Semiconductor & Electronics

    Specialized inflatable seals can be used in controlled manufacturing environments where contamination control and reliable enclosure sealing are important.
