Pipe Plug, Test, Muni Bypass 130-2 Series
These Muni Ball Bypass Plugs are ideal for testing and/or pressure monitoring piping systems. They are used to ease installation and repair of residential or commercial piping systems. Smaller plugs are inflated through a Schrader type tire valve and larger diameter plugs inflate through a ¼” or ½” Male Quick Disconnect with an NPT plug connection.
To Convert the Muni Ball into a Remote Placement Plug, please refer to the Accessories.

The Muni Bypass 130-2 Series pipe plug isolates pipeline sections while allowing flow through an integrated bypass connection. These plugs are commonly used in municipal water, wastewater, and industrial systems during testing, inspection, or repair work. The bypass connection allows flow to continue while crews perform testing or repairs on the isolated sections while keeping systems operational.
How does the Muni Test Bypass Pipe Plug Work?
The plug operates using pneumatic inflation and a bypass connection that redirects flow around the isolated section. Once positioned at the target location within the pipeline, compressed air inflates the plug body, creating a pressure-activated seal against the pipe wall. This seal isolates the downstream section from upstream flow and pressure.
Meanwhile, the integrated bypass mechanism channels flow through an external hose or pipe system connected to inlet and outlet ports on the plug assembly. This maintains service continuity during testing procedures or repair work. The inflation pressure adjusts based on pipe diameter and working conditions, ensuring the seal remains secure while flow diverts safely around the work zone. Deflation reverses the process, allowing quick removal once the job completes.
Key Beneficial Features of Muni Test Bypass Pipe Plug
Our design philosophy prioritizes both operational efficiency and worker safety across diverse municipal and industrial applications. The following features distinguish our Muni bypass 130-2 series from conventional plugging solutions.
- Effective Sealing: We engineer each Muni ball pipe plug with advanced elastomer compounds conforming precisely to varying pipe surfaces, accommodating minor irregularities and corrosion patterns common in aging infrastructure. This ensures leak-free isolation in older infrastructure, even during extended operations.
- Durable Construction: Our plugs withstand repeated inflation cycles and harsh wastewater environments without compromising structural integrity. Reinforced body design resists debris abrasion, reducing replacement frequency and reducing replacement frequency.
- Simplified Installation Process: These bypass test plugs require minimal crew training and can be positioned quickly using standard deployment equipment. Straightforward bypass line connection points eliminate complex assembly procedures, allowing teams to establish flow diversion faster than alternatives.
- Versatile Size Range Compatibility: We manufacture the Muni bypass 130-2 series to accommodate various pipe diameters commonly encountered in municipal infrastructure. This versatility allows maintenance departments to standardize inventory, while addressing different project requirements.
Industry-Wise Applications of Bypass Test Plug
The versatility of our Muni test bypass pipe plug extends across numerous sectors where flow must remain active during maintenance. Our Muni ball pipe plug serves a variety of critical applications, including:
- Municipal Water Distribution Systems: These plugs facilitate hydrostatic testing on repaired main lines while residential and commercial customers receive uninterrupted service.
- Wastewater Collection Infrastructure: Sanitary sewer rehabilitation projects depend on these bypass test plugs to divert flow safely during CIPP lining installations, manhole repairs, and section replacements.
- Industrial Process Piping: Manufacturing facilities use these plugs to isolate pipeline sections for inspection or modification without halting production. Chemical plants, food processing operations, and pharmaceutical manufacturers maintain critical process flows through bypass lines during essential maintenance activities.
- Storm Water Management Systems: These Muni ball pipe plugs redirect flow during storm sewer inspections and repairs, preventing flooding during heavy precipitation events.
- Power Generation Facilities: Cooling water system maintenance in thermal power plants relies on these bypass test plugs to maintain continuous circulation during repairs. The equipment withstands demanding pressure and temperature conditions typical in these applications without experiencing premature failure.
- Commercial Building Services: Property management companies and plumbing contractors deploy these plugs when working on large building systems where shutting down risers or mains would disrupt multiple tenants.

Frequently Asked Questions
- Can these bypass test plugs handle solids-laden flows common in wastewater applications?
Yes, our Muni bypass 130-2 series accommodates wastewater containing typical solids content. Bypass ports prevent clogging from debris while maintaining adequate flow rates.
- What bypass flow capacity can I expect from your Muni test bypass pipe plug?
Bypass capacity depends on plug size, bypass hose diameter, and system pressure. Our engineering team calculates expected flow rates to verify that the bypass system handles your operational requirements during isolation.
- How long can a Muni Bypass 130-2 Series plug remain inflated in a pipeline?
Our plugs maintain reliable sealing for extended periods, supporting multi-day projects when properly monitored. We recommend periodic pressure checks and provide guidelines for maximum deployment duration based on conditions.
- What maintenance do these bypass test plugs require between uses?
Basic maintenance involves cleaning debris, inspecting for cuts or abrasions, checking inflation valve function, and proper storage away from sunlight and ozone sources. Following maintenance protocols significantly extends service life.
- Can your plugs be used in pressurized systems or only in gravity flow applications?
Our Muni ball pipe plugs function in both pressurized and gravity systems. Inflation pressure adjusts to exceed line pressure by a safe margin. We provide pressure rating information matching your conditions.
- Can these plugs seal effectively in pipes with significant internal corrosion or tuberculation?
Our flexible design compensates for moderate surface irregularities typical in aging metallic pipes. For severely corroded sections, assess pipe condition to determine if cleaning or alternative sealing methods better serve.
