Where water flow needs to be stopped, inflatable stoppers are an efficient solution. By creating an airtight seal within the pipe, they effectively stop the water flow to enable professionals in different industries to do their job and resolve the situation. Inflatable Pipeline stoppers insure a perfect tightness and an excellent back-pressure resistance. Made from high quality fibre-reinforced elastomer our Inflatable Pipeline stoppers give you a high level of reliability.
