Of donut shap, the inflatable annular seals are highly efficient in sealing, isolating, tightening, clamping, pressing and handling applications.

They fit onto silo or hopper gutters, tubes and often serve as inflatable seals. Tailor-made, various materials and accessories are offered to adapt to your environment and your usage constraints: pressure, temperature, chemicals in contact, service life, mounting, etc.

APPLICATIONS
Sealing two tubes
Ensuring sealing between a big-bag and a filling head with an inflatable seal
Simulating field pressure
