Flat and 3D Doughnut Seals

Inflatable seals are elastomeric tubes designed to round out with the introduction of air to form a tight barrier between a mounting and striking surface. Pronal Flat and 3D doughnut seals are a derivative of their lifting bag products.

Thanks to their high mechanical resistance, these seals are used for applications where a perfect seal is required.

Typical uses include:

  • Sealing
  • Pressing
  • Handling
  • Flanging
  • Isolating
