Inflatable Line Stop Selection
Highest Pressure: 129-0 Series
Highest Flow Rate: 129-8 Series
Smallest Tap Size: 128-0 Series
Reduce Time and Cost with Petersen® Inflatable Line Stop (ILS) systems. Call Petersen or email to discuss the benefits.
- 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 flexible insertion through a much smaller hot tap than mechanical Line Stops
- IFS Insertion Systems may be used with multiple plug and pipe sizes.
- Other pressures, sizes, and configurations available

Note: It is best to stop the flow during the installation of PeteStopTM line stops. If not practical the below “rule of thumb” maximum flow rate seems to be acceptable.
1/2 ft/sec for the 129-0 series standard and high pressure plugs
10 ft/sec for the 129-8 series Flow Stop plugs
