Hydrostatic Test / Isolation Plugs
Safe, effective solutions for rapid testing and repairs
  • Test Open End Pipes, Pipelines, Tubes and Pressure Vessels
  • Perform Flange-To-Pipe Weld Testing
  • Isolate and Test Pipe Connections

EST Group offers a complete line of hydrostatic test plugs and isolation plugs for pressure testing of pipe, pipelines and pressure vessels. Test plugs provide safe and effective testing at working pressures up to 14,000 psi (960 Bar). Pipe OD and ID sealing versions available.

Isolation plugs are designed for quickly isolating and hydrostatically testing weld joints of any welded flange-to-pipe connection as well as isolating pipe ends during cutting, grinding and welding operations.

Also available are hydrostatic test pumps that are ideal for use with our entire range of pressure test plugs.
