Pipe testing plugs are designed for a wide range of industrial and domestic applications. According to the manufacturer, such plugs are ideal for pressure testing of all pipe work systems, blocking of pipes and orifices to prevent the ingress of unwanted material, and weld purging applications. Each plug is comprised of two plates on a central hollow waterway with an expandable rubber seal between the plates, which compresses to seal inside the opening of a pipe when the wing nut is turned. Three styles - nylon, aluminum, and steel - are available. They come in sizes to suit pipes and orifices from 1/2 – 72 inches (12-2,000 mm) in diameter.
