The Pipestoppers Division at Huntingdon Fusion Techniques HFT® has designed and manufactured a range of mechanical and inflatable Pipestoppers and Plugs for a variety of applications.
The Low Profile Stopper is available for applications where insufficient length of pipe is available for the regular Cylindrical or Spherical Inflatable Stopper. These stoppers are available in sizes 6 inches to 88 inches. According to the company, they provide excellent grip inside the pipe, with an effective airtight seal.
