Canvas inflatable air bags are a light duty stopper, ideal for use where the pipe access is smaller than the pipe diameter. The air bag can be fully deflated and inserted into the opening, then inflated once inside to create an air-tight seal.
Canvas air bags are available in sizes to suit pipe diameters from 50-300mm, and water back pressures from 3-10 psi depending on the size of air bag selected. As standard, all canvas air bags include a 1.2m inflation hose with a brass tap.
