Expanding Pipe Stoppers are designed for the effective sealing of pipe ends during low-pressure testing, maintenance and pipeline installation.
Manufactured using a robust mechanical expansion design, these stoppers create a reliable internal seal that prevents the passage of liquids, gases or debris. They are widely used across industrial applications where temporary isolation or testing is required.
Suitable for a wide range of pipe diameters and materials, Expanding Pipe Stoppers provide a simple, reusable and cost-effective solution for pipeline control.
Important:
Maximum back pressure must not exceed 20% of the inflation pressure

Each pipe stopper consists of a central shaft fitted with metal pressure plates and a rubber sealing element.
When the unit is tightened, the rubber element is compressed between the plates, causing it to expand radially against the internal wall of the pipe. This expansion creates a tight seal, allowing the pipe to be isolated or tested safely.
