  • Safety enhanced and Environmental Risk reduced with smaller hot tap hole to help maintain pipeline integrity.
  • Conforms to out of round pipe configurations for better seal than mechanical stops.
  • Time and Cost reduced with smaller lighter weight equipment allows and faster deployment.
  • High flexibility, small deflated diameter allows installation through much smaller hot tap than much heavier costlier mechanical stops.
  • Heavyweight Ballistic Nylon reinforced Polyurethane construction for long term reuse. Materials such as Kevlar and Viton available for most pressure, chemical, and temperature requirements.
  • A minimal inflation pressure with water, air or other inert gas will expand the plug thus most of the pressure is applied to pipe ID for sealing.
  • Small deflated plug diameter allows insertion through a much smaller hot tap than mechanical Line Stops
  • IFS Insertion Systems may be used with multiple plug and pipe sizes.
