Low Pressure Inflatable Pipe Plug / Balloon Plug

Inflatable Balloon Test Plugs are the Most Flexible Available with the Greatest Range of Sizes - Available for Sale or to Rent

USA Industries' Inflatable pipe plug, also known as a balloon plug, expands to temporarily isolate pipes during repairs, or in the event of a spill. Inflatable plugs are available for isolating piping in line sizes from 1.5" through 66".

The innovative design allows the isolation plug to be smaller and more flexible which means it can be snaked through hot tap or branch pipes into larger pipelines that are otherwise inaccessible. Inflatable pipe plugs can inflate up to 8 times it's compact size to prevent the flow of liquids during maintance work or to block pipes or drains in the event of a spill (connects with your air compressor). The compact size also means that this plug takes up minimal storage.

While no isolation plug is one size fits all, USA Industries' balloon plug conforms to a wide range of line sizes and can inflate fully or partially to fit your application.

A SPECIAL WORD OF CAUTION: Pressure testing can be an extremely hazardous operation and safety precautions should be strictly adhered to. All connections, valves, flanges and other fittings should be checked for suitability to test pressure. Verify the line ID & Plug Range match. Most importantly - Never stand or pass in front of any test plug or other enclosure while test is in progress. If plug discharges during a test, serious injury or death could occur.
