Inflatable Pipe Test Plug with Quick-Install Hose
This versatile kit includes an inflatable pipe plug, a 19.4-inch extension hose, a steel chain, and an anti-falling steel ring. Made from 4.5mm thickened natural rubber, it is designed for 2-inch pipes with strong expandability. Double pull ring design aids removal, and copper valves ensure reliable sealing. Inflation up to 2.18 PSI is supported to achieve a firm seal during tests or water blocking tasks.
Inflatable Pipe Plug With Accessories (4 Inch)
This 4-inch capable inflatable plug comes with an extension hose of 40 inches, valve core key, and extra clips. It is designed for multi-pipe compatibility—useful for PE, HDPE, PVC, metal, and cement pipes.

Inflatable Pipe Plug (24 inch)
This high-coverage plug is designed for large-diameter pipes, with a 24-inch nominal size and a broad sealing surface. It ships with a flexible selection of accessories designed to extend inflation distance and improve ease of use. The plug uses natural rubber with good expansion and memory, making it suitable for diverse pipe maintenance, testing, and temporary water blocking tasks, including many common residential and commercial lines.
Buying Guide
- Pipe size compatibility: Select a plug that matches or slightly exceeds the target pipe diameter. Many models list workable ranges from about 1.25 inches up to 4 inches or more.
- Material and memory: Look for robust natural rubber or reinforced rubber blends with good memory to form a tight seal after inflation and removal.
- Inflation method and pressure: Manual pumps are common; verify the maximum safe pressure (commonly around 2.0–2.9 PSI) to avoid pipe damage.
- Extension hose length: A longer hose simplifies distant placement and reduces the need to reposition equipment during testing.
- Additional accessories: Valves, clips, extension hoses, and removal aids (like a double pull ring or steel components) can improve setup speed and reliability.
- Operational flexibility: Some plugs support air or water inflation and include relief valves to avoid overinflation, enhancing safety for field use.
- Durability and warranty: For frequent use, prioritize models with durable construction and reliable sealing performance across temperature variations.
When selecting an inflatable pipe plug, consider your typical pipeline systems (plastic, metal, or concrete) and the most common diameters you encounter. A kit that includes a few sizes and a long extension hose offers flexibility for diverse projects. Always follow manufacturer guidelines for cleaning pipes before insertion and for safe inflation to prevent leaks or pipe damage.
