Allpipe stock and supply a range of mechanical pipe stoppers with natural rubber (NR) seals suitable for basic air tests up to 0.5bar / 5m head of water. Air test kits can also be purchased. As standard, all of the pipe stoppers come with blank end caps.
Both our aluminium and steel pipe stoppers can also be used for a range of other applications where temporary seals are required, whether indoors or outdoors. If looked after, a mechanical pipe stopper can last many years.
