Overlaps Seals

Overlaps Seals are open inflatable seals that are designed to create a water and airtight seal between two cylindrical components. Because these seals are open, they can be easily positioned and installed even in a narrow space. Their two chamfered ends can be overlapped, creating a perfect seal when they are inflated.

Overlaps Seals are used for:

  • repairing corrosion damage,
  • ensuring a seal around pipes for welding operations.
