The total length of the main body is short and easy to handle! A total of 10 types tailored for pipe diameters from 75 to 300 mm.
The "Stop Water Ball Short Type" is a device that uses a stop water ball tailored to the pipe diameter, designed for temporary water stoppage during tasks such as cleaning, dredging, various inspections, tests, and repairs within the pipe. It expands by injecting air using a foot pump or compressor, creating a tight seal against the pipe's interior to stop the water flow. Additionally, the version with a bypass can be used for various tests such as pressure tests and water-tight tests, as well as for water replacement work. It is available in a total of 10 types: 5 sizes without a bypass and 5 sizes with a bypass, suitable for pipe diameters ranging from 75 to 300 mm.
