Flexible Double Test Plugs
1-1/2" - 8" Diameter, Center to Center Distances to 96". One double mechanical test plug does the work of three plugs. Both balls on the 1-1/2" and 2" plugs release with the same handle, the lower ball, however, releases before the upper ball. The 3" - 8" double test ball plug sizes have two handles so each ball can be released separately.
Typical Installations
The ball is molded of pure rubber, molded parallel ridges insure perfect seal. Castings are of non-rust aluminum. Handles are of coated steel. All parts are replaceable. Blowouts and water damage are prevented because the double mechanical test plug allows the system to be drained prior to its removal. The flexible spring bends to any angle to effectively test from any type fitting.

What are Double Mechanical Test Plugs?
Double mechanical test plugs are essential devices designed for low-pressure pipeline sealing applications. These plugs are made with molded rubber, precision aluminum, and steel to create an effective and tight seal.
These 149-2 series plugs are available in variety of sizes which can replace multiple single plugs, providing a cost-effective alternative. Double mechanical test plugs are made from durable materials and feature a flexible design, which helps to effectively prevent blowouts and water damage. This makes them perfect for various testing situations in both plumbing and industrial applications.
Benefits of using Double Mechanical Test Plugs
Double mechanical test plugs come with various advantages which improve their performance and efficiency in low-pressure sealing applications. These benefits lead to more effective testing procedures and enhanced safety during pipeline maintenance.
Here are some of the main benefits:
- Efficiency – Double mechanical test plugs can effectively replace the function of three single plugs. This design simplifies the testing process which allows operators to perform tests more quickly and effectively, saving time on pipeline maintenance and repair.
- Cost-Effectiveness – These pipe plugs are cost-effective as they reduce the need of using multiple plugs for low-pressure sealing requirements. As fewer components are needed, customers can reduce material costs and storage requirements, resulting in improved overall resource management.
- Prevention of Blowouts and Water Damage - The unique design of double mechanical test plugs allows for safe system drainage before removal. The design reduces the chance of blowouts and water damage while ensuring that any extra pressure is safely released. These plugs improve operational safety by allowing for regulated drainage and protecting the pipeline system's integrity during testing and maintenance.
Applications of Double Mechanical Test Plugs
Double mechanical test plugs are flexible tools with a wide range of applications across various industries. Their reliable sealing features and efficient design make them suitable for the following applications:
- Construction Projects: In construction, these plugs are used for sealing off pipelines during the initial phases, allowing testing to proceed without leakage. They play an important role for ensuring the integrity of water lines and drainage systems during the construction process.
- Water Treatment Facilities: In water treatment facilities, double mechanical test plugs make it easier to maintain and test piping systems. They help with isolating areas of the system for inspection or repair, ensuring water quality and allowing for efficient cleaning and maintenance activities.
- Pipeline Maintenance and Testing: These plugs are crucial for pipeline maintenance and testing. They allow operators to execute pressure tests in a safe manner, guaranteeing the pipeline's integrity before resuming operation. The ability to drain the system before removal improves safety and prevents potential hazards like as blowouts or leaks.
