Pipe Plug, PeteStop® Inflatable Line Stop - 129 Series
Quickly Block the Flow without depressurizing the pipeline!
The Petersen® PeteStop® 129-Series Line Stop is our best selling system. It is a great choice to complement a mechanical stop or use in place of because of its savings in time, money and lighter, more flexible installation. Plus the PeteStop® Inflatable Line Stop is able to handle more difficult pipe conditions where a mechanical stop would be unable to get a workable seal.
Advantages of PeteStop® 129-Series Pipe Plug Systems
- Faster – smaller lighter weight equipment
- Less Expensive – smaller hole and smaller equipment needed, less time to complete
- Safety Enhanced - smaller tap hole and larger surface area means less stress on pipe
- Lower Environmental Risk – smaller tap hole
- Plug Abnormal Pipe Conditions - Heavy Corrosion, Out-of-Round Pipe, Weld Bead, etc.
- Versatility – Most pressure, chemical, temperature requirements
- Limited Space Work Environment
- Minimal pressure to seal on pipe ID
- Multiple combinations – Double Block & Bleed, Centered, Off-Center, Side, Flow Stop, High Pressure
- Reusable – Heavyweight Ballistic Nylon reinforced Polyeurethane (Kevlar, Viton & others available)
- Conform to the pipe better
- Line Stop at pipe bend or near pipe bend
- Less Stress on Pipe with Structural Integrity Issues or Aging Pipe versus Mechanical Stop
- Great Complement to Mechanical Stop where there isn’t a workable seal
- Stop flow in pipes over 50”!!
Product Instruction Manual 129 Series
PeteStop® 129-Series Configurator
Note: It is best to stop the flow during the installation of PeteStop® line stops. If not practical, the below maximum flow rate “rule of thumb” 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

What Problems Can the PeteStop® 129-Series Line Stop Solve?
The Inflatable Line Stop Plugs by Petersen Products are designed to handle some of the most common and difficult pipeline issues that engineers, contractors, and utility personnel encounter. Whether you're working on active pipelines, corroded infrastructure, or in confined locations, the 129-Series offers a versatile and reliable option.
- Works Without Depressurizing the Line - Traditional methods frequently require shutting down a pipeline, which is both costly and time-consuming. The PeteStop® 129-Series lets you to isolate parts of pressurized pipelines without fully depressurizing them, reducing downtime and keeping systems operational.
- Seals Difficult Pipe Conditions - Mechanical stops may struggle with pipes that are out of round or heavily corroded. The inflatable design of the 129-Series conforms to irregular surfaces, making it excellent for aging infrastructure and pipelines including weld beads, scale buildup, or deformation.
- Performs in Tight or Limited-Access Areas - The 129-Series is compact and lightweight, allowing for easy installation even on cramped construction sites. It's ideal for tight spaces or restricted access, such as near bends, offsets, or inside utility vaults.
Each of these problem-solving capabilities saves time, labor, and risk, making the 129-Series a reliable choice for important pipeline maintenance and repair.
Why Choose Inflatable Plug Line Stops Over Mechanical Alternatives?
Inflatable plug line stops, such as the PeteStop® 129-Series, offer significant advantages over typical mechanical stops, particularly in challenging environments.
- Seals Irregular and Damaged Pipes - Inflatable plugs fit into out-of-round, corroded, or welded surfaces where mechanical stops frequently fail to seal properly.
- Reduces Pipe Stress – These inflatable plugs reduce mechanical strain on aged or fragile pipes due to their increased surface area and low insertion pressure.
- Performs Under Pressure - The PeteStop® 129-Series is designed for use in pressurized systems and allows for safe flow isolation without requiring system shutdown or depressurization.
- Lighter, Faster Setup - The lightweight design makes handling and installation easier, saving time and avoiding the need for heavy equipment.
These benefits make inflatable plug line stops the better option for live system maintenance, retrofit works, and pipelines with structural issues.
Common Use Cases for the PeteStop® 129-Series Inflatable Line Stop
Contractors and engineers trust inflatable line stopping when mechanical methods fail or shutdowns are too costly. The PeteStop® 129-Series is particularly useful in the following scenarios:
- Mid-Project Flow Isolation - Maintain pipeline pressure while isolating a section for inspection, repair, or change, without disrupting system operations.
- Temporary Flow Diversion - Using inflatable line stopping, you can safely redirect flow around a work area while bypassing damaged or aging parts.
- Valve Replacement Without Drainage - Replace or repair valves on live lines without having to drain entire systems, saving time and water.
- Hazardous Line Containment - Stop flow safely in lines carrying chemicals or other hazardous materials to reduce risk during an emergency or regular repair.
Every scenario highlights how inflatable line stopping simplifies challenging tasks while ensuring system availability and worker safety.
