Horobin’s range of inflatable PVC sealing and testing bags are ideal for use in all types of plastic pipes. The ridges around the circumference of the sealing bag prevent the bag slipping down the pipe and can also be used in vertical soil stacks. The PVC sealing and testing bags are easily inflated for trouble free pipe sealing and testing and are ideal for use in areas where access is smaller than the test diameter; extension hose is also available to facilitate remote sealing and testing. These PVS testing bags are available for pipe diameters from 25mm to 450mm.
