Pipe Plug, Multi-Flex®, Oil Res. Heavy Duty, 124 Series

The Multi-Flex® 124 Series Heavy Duty Oil Resistant Multi-Flex Pipe Plug is designed for blocking, testing, and isolating pipelines in demanding industrial and municipal environments where resistance to oil, fuel, grease, and hydrocarbons is required. Built with a heavy-duty elastomer body and reinforced construction, this inflatable pipe plug provides dependable sealing performance in pipelines exposed to petroleum-based fluids and harsh service conditions.

The Heavy-Duty Oil-Resistant Multi-Flex Pipe Plug is commonly used for sewer maintenance, industrial pipeline isolation, hydrostatic testing, and repair work. Its flexible design allows the plug to conform to out-of-round pipe conditions while maintaining a secure oil-resistant plug seal. The rugged construction supports repeated use in challenging environments, making it suitable for contractors, municipalities, refineries, petrochemical facilities, and industrial maintenance crews.

Available in a wide range of pipe sizes and configurations, the Multi-Flex® 124 Series is engineered for reliable performance in both standard and complex pipeline applications.

Key Features and Benefits of the Heavy-Duty Oil-Resistant Multi-Flex Pipe Plug

• Oil Resistant Elastomer Construction
  The Heavy-Duty Oil-Resistant Multi-Flex Pipe Plug is manufactured using oil-resistant materials designed to withstand exposure to fuels, oils, lubricants, and petroleum-based chemicals commonly found in industrial pipelines.
• Heavy Duty Reinforced Design
  The reinforced construction provides added durability for demanding applications involving higher back pressures, repeated installations, and rough operating environments.
• Flexible Multi-Flex® Body
  The flexible body design helps the plug conform to irregular, aging, or slightly out-of-round pipe surfaces, improving sealing performance across various pipe materials.
• Wide Range of Applications
  Suitable for:
  • Sewer and drain maintenance
  • Industrial pipeline isolation
  • Hydrostatic pipe testing
  • Valve replacement projects
  • Petrochemical and refinery maintenance

  The inflatable design allows quick installation through small access points, reducing setup time during maintenance and repair operations.

• Multiple Pipe Compatibility
  The Heavy-Duty Oil-Resistant Multi-Flex Pipe Plug can be used in:
  • Steel pipe
  • Cast iron pipe
  • Concrete pipe
  • PVC pipe
  • Ductile iron pipe
  • HDPE pipe
• Reusable Construction
  Designed for repeated use when properly maintained and operated according to recommended procedures.

How the Heavy Duty Oil Resistant Multi-Flex Pipe Plug Works

The Heavy Duty Oil Resistant Multi-Flex Pipe Plug is inserted into the pipeline in a deflated condition. Once positioned correctly, the plug is inflated to the recommended inflation pressure using air or another approved inflation medium. As the plug expands, it presses securely against the inside pipe wall to create a temporary seal.

The Multi-Flex® design allows the plug to adapt to slight pipe irregularities and maintain reliable contact with the pipe surface. This helps create an effective seal for blocking flow, conducting pipeline tests, and isolating sections for repairs.

Depending on the application, the pipe plug may be used for:

• Flow stopping
• Pipeline testing
• Temporary isolation
• Maintenance shutdowns
• Leak testing
• Repair support operations

For bypass applications, Multi-Flex® Oil Resistance Bypass Pipe Plug is available to allow controlled flow through the center of the plug while maintaining pipeline isolation.

Applications and Use Cases

The Heavy-Duty Oil-Resistant Multi-Flex Pipe Plug is used across municipal, industrial, and commercial operations where oil resistance and heavy-duty performance are required.

• Industrial Pipeline Isolation
  Used to temporarily isolate sections of pipe during maintenance, inspections, repairs, and equipment replacement projects.
• Sewer and Drain Maintenance
  Ideal for blocking sewer lines and drain systems during cleaning, rehabilitation, and inspection operations.
• Hydrostatic Testing
  The Heavy-Duty Oil Resistant Multi-Flex Pipe Plug can be configured during hydrostatic pressure testing to seal pipe ends and isolate test sections.
• Petrochemical and Refinery Operations
  Suitable for pipelines exposed to oil-based fluids, hydrocarbons, and industrial chemicals commonly found in refinery and processing environments.
• Valve Replacement and Repair
  Used to isolate pipe sections during valve replacement, pipe repairs, and maintenance shutdowns.

Safety Guidelines and Operating Instructions

Proper operation of the Heavy-Duty Oil Resistant Multi-Flex 124 Series Pipe Plug is important for safe and effective performance.

• Follow Inflation Pressure Guidelines
  Always inflate the pipe plug to the recommended inflation pressure listed for the specific plug size and application. Overinflation may damage the plug or pipe.
• Verify Pipe Conditions
  Inspect the pipe for debris, sharp edges, or damaged surfaces before installation to help prevent plug damage.
• Secure the Plug Properly
  Ensure the plug is positioned correctly inside the pipe before inflation. Use proper restraint systems when required.
• Monitor Back Pressure
  Never exceed the maximum allowable back pressure rating for the plug. Excessive back pressure can cause plug movement or failure.
• Follow Manufacturer Instructions
  Each plug has a unique pressure rating. Always refer to Petersen operating instructions and pressure recommendations for the specific pipe plug model being used.
