125 Series Multi-Flex® Oil-Resistant Bypass Pipe Plug is designed for pipeline isolation and bypass, providing reliable support in industrial, oil, and chemical-resistant environments. These plugs, made of Nitrile Reinforced Ballistic Nylon, offer improved oil resistance, flexibility, and durability under severe environments.
Designed for high-pressure conditions, the 125 Series ensures secure pipe blocking and regulated bypass flow, making it a vital tool for pipeline maintenance, testing, and emergency repairs. The mix of lightweight, puncture-resistant materials and reinforced synthetic rubber extends the plug's life and improves performance in chemical, wastewater, and industrial pipeline applications.
Key Features & Benefits of 125 Series Multi-Flex® Oil-Resistant Bypass Plugs
- Enhanced Oil and Chemical Resistance - The synthetic nitrile rubber construction increases durability and extends the plug's life.
- Lightweight & Flexible Design – It is easier to handle than molded rubber plugs, lowering strain and labor expenses.
- Puncture & Tear Resistant - Reinforced materials can tolerate harsh circumstances and heavy use.
- Higher Pressure Capabilities - Outperforms ordinary gas pipe plugs in harsh industrial situations.
- Adaptable and Multi-Use - Fits many pipe diameters and shapes, making it excellent for maintenance, testing, and repairs.
- Bypass Capability - Built-in ports allow for controlled fluid flow during pipeline work.
- Easy Storage and Transport - The small deflated design saves space and makes handling easier.
- Tether Loops on Both Ends - Provides a tight grip and easy retrieval.
How It Works: Inflation & Bypass System
The 125 Series Multi-Flex® Oil-Resistant Bypass Plug features an innovative inflation and bypass mechanism to provide effective pipeline isolation and maintenance. This method allows accurate pressure control, regulated fluid movement, and seamless connection with other plugs for larger-scale applications.
- Precise Inflation and Monitoring - The plug features inflation monitoring ports that enable for precise pressure adjustments. This provides a secure and stable seal, lowering the possibility of leaks or failures during testing or maintenance.
- Controlled Bypass Functionality - Built-in bypass ports allow for regulated fluid circulation through the pipeline without removing the plug. This function is suitable for maintenance procedures that require uninterrupted flow while isolating specific areas.
- Expandable Series Connection - The plug can be coupled to other units to provide coverage in bigger pipelines. Because of its flexibility, it is ideal for complex industrial applications requiring many components to be separated or tested at the same time.
With this advanced mechanism, the 125 Series Pipe Plug improves safety, efficiency, and adaptability in high-pressure, chemically resistant environments.
Applications and Use Cases
125 Series Pipe Plug is a versatile tool suitable for a variety of industrial applications. Its durable, oil-resistant design makes it appropriate for difficult environments requiring reliable pipeline isolation and control.
- Pipeline Isolation & Testing - Seals off parts of oil, gas, and industrial pipes for pressure testing, maintenance, and inspection.
- Drainage and Sewer Systems - Helps with flow management in wastewater and drainage applications, preventing backflow and ensuring efficient repairs.
- Maintenance and Emergency Repairs - Offers a simple and secure way to block or bypass pipeline sections during scheduled maintenance or urgent repairs.
- Industrial and Chemical Processing - The plug's reinforced nitrile rubber and ballistic nylon structure makes it resistant to severe chemicals, oils, and extreme working conditions.
125 Series Pipe Plug's durability, flexibility, and adaptability make it a vital tool for pipeline maintenance, testing, and repair professionals.
Safety & Operating Instructions for 125 Series Multi-Flex® Oil-Resistant Bypass Plugs
Proper safety precautions ensure that the 125 Series Multi-Flex® Oil-Resistant Bypass Pipe Plug operates reliably and securely.
- Proper Inflation Guidelines - Always use a regulated air supply and regularly monitor pressure levels. Overinflation can result in damage or failure. Check the inflation monitoring ports to ensure correct pressure control.
- Recommended Pressure Limits - Each model has a unique pressure rating. Always follow the manufacturer's guidelines to ensure safe operation within the authorized limits. Exceeding these restrictions may jeopardize the plug's efficacy and safety.
- Secure Handling and Retrieval - Attach tether loops to both ends before deployment to ensure control during insertion and withdrawal. To avoid sudden movements, slowly release pressure and maintain a clean, stable environment when retrieving.
By following these best practices, users can maximize safety, extend the lifespan of the plug, and ensure effective pipeline isolation and maintenance.
