High Pressure Test Plugs

GripTight® High Pressure Test Plug - Test Open    End Pipes, Pipelines, Tubes and Pressure Vessels      Quickly and Safely •   Unlike other plugs that can loosen and eject under  high pressure - even becoming dangerous     projectiles the GripTight actually uses test pressure    to seal more securely against the pipe's inner     diameter. •   The greater the pressure - the greater the grip! The      result is safer installation, better sealing and all around safer testing.
