Working Mechanism

  • The plug is placed inside the opening of the pipe which needs to be sealed / blocked for testing.
  • Users need to connect the end of the inflation hose to the fitting on the plug, while the other end of the inflation hose should be connected to the pump or line pressure.
  • The plug is inflated using the pump connected to the inflation hose.
  • The inflated plug blocks / seals the pipe for testing tasks.
  • After testing, the inflation hose should be deflated & removed first, and then the plug should be deflated.

Features
