Pneumatic stopper type FOG/NO is suitable to plug temporarily egg-shaped section pipes like sewer lines; drainages etc. in order to separate totally the section of the pipe containing the liquid from the section where it is necessary to make a repair or maintenance work. This pneumatic stopper ( together with type FOG/SO ) can be used to carry out pressure tests on pipes where the test fluid can be placed into the pipe through some opening.

Pneumatic stopper can be inflated with air or nitrogen through a flexible hose fitted with a valve and a safety vent valve. This stopper is made with synthetic fabric coated on both faces with plastomers resistant to water based and non corrosive liquids.
