Pneumatic sealing equipment designed for spot repair of open joints, cracks and infiltrations in pipes without the need for excavation. The packer isolates the damaged zone between two inflatable balloons, allowing direct action on the defect from inside the pipe. No bypass — its function is exclusively sealing and spot repair. Available in a wide diameter range from DN 70 to DN 1500.
| Diameter range | DN 70 – DN 1500 |
| Max. inflation pressure | 0.1 – 0.35 MPa (depending on model) |
| Airbag length | 530 – 2,000 mm (depending on model) |
| Material | Reinforced rubber + metal frame |
| Applications | Spot repair of joints and cracks, infiltration sealing |
| Operation | No excavation, from inside the pipe |
Selection of the most common models. In addition to the standard range, we manufacture custom packers for special diameters, lengths and configurations — no-obligation enquiry.

In addition to the standard range, we manufacture custom packers for projects with special requirements: out-of-range diameters, custom lengths, different working pressures or double-balloon configurations for simultaneous injection.
