Expansion seal

A sealing material with a different structure from conventional seals! An expandable seal that enables the design of new equipment and devices.

The "expansion seal" has a different structure from conventional sealing materials, allowing for the design of new equipment and devices. Unlike traditional gaskets, it does not need to be pressed against external pressure; instead, the product itself expands to create a seal. It adapts well even if there are slight distortions, undulations, or irregularities on the sealing surface, demonstrating excellent sealing functionality, making it suitable for areas that open and close like doors or where there are fluctuations in the sealing surface. [Features] ■ A structure different from conventional sealing materials ■ Enables the design of new equipment and devices ■ Seals by the product itself expanding ■ Suitable for areas with fluctuations in the sealing surface *For more details, please refer to the PDF document or feel free to contact us.

New Masheel: Air Expansion Seal

It is possible to propose seals tailored to applications with a rich variety of cross-sectional shapes. Production of small diameters of 60mm or less is acceptable.

It can be used as a seal for valves, autoclaves, clean room doors, etc. ● I want to seal a wide surface quickly and with high airtightness. ● It has high load-bearing performance and a long lifespan. ● It maintains high airtightness under vacuum and pressure. ● I want to simplify auxiliary equipment using only pneumatic pressure. ● It is difficult to achieve flatness and finishing precision on the sealing counterpart surface. ● It has high durability even when frequently exposed to pressure fluctuations. ● I want to implement automatic pressure monitoring.

Pressure-type expansion seal "Tube Seal"

Can seal large gaps! Pressure management allows for adjustment of sealing surface pressure.

The "TUBE SEAL" expands (inflatable) by being pressurized with a fluid (air, water, oil, etc.), sealing gaps and demonstrating its sealing function. It can seal large gaps and can follow the irregularities, distortions, misalignments, and vibrations of the sealing surface. Additionally, it allows for pressure management and on/off adjustments via remote control, and the sealing surface pressure can be adjusted through pressure management. 【Features】 ■ Capable of sealing large gaps ■ Can follow the irregularities, distortions, misalignments, and vibrations of the sealing surface ■ Allows for pressure management and on/off adjustments via remote control ■ Sealing surface pressure can be adjusted through pressure management ■ Specifications can be designed separately according to application *For more details, please refer to the PDF document or feel free to contact us.
