The pneumatic stopper type FOG/NO is suitable for the temporary filling of pipes with ovoid section, such as sewerage systems, drainage etc. in order to completely separate the section of the pipeline containing the liquid from the section where repair or maintenance is to take place. The pneumatic plug (together with the FOG/SO type) can be used for the performance of the pipe pressure tightness tests where the test fluid can be introduced into the pipe from other openings.
The stopper (only for large sections) is also equipped with handles for correct positioning in the pipe. The pneumatic stopper type FOG/NO is inflatable with air/nitrogen through a flexible tube equipped with inflation valve and a vent valve. The stopper is made of synthetic fabric covered with plastomers resistant to aqueous liquids and non-corrosive liquids in general.
