Pneumatic shutter G

rubberfor pipes

Inflating pressure from 0.4 to 1.8 bar Standard diameters from 100 to 1800 mm The pneumatic stopper type G is used to plug temporarily circular pipes like pipelines and gas lines at relatively low pressures; for this purpose this stopper is fitted with 2 sealing rings which enhance the resistance to the residual pressure in the line. This pneumatic stopper is made with synthetic fabric coated on both faces with oil resistant plastomers; the elasticity of its diameter is such to allow a perfect sealing in the pipe. After its correct positioning into the pipeline thanks to the two handles, the stopper can be inflated with air or nitrogen through the flexible hose fitted with a valve and a safety vent valve
