Expandable test plugs for purging and general pipe blocking Pipe stoppers, or drain plugs as they are sometimes known, are used to temporarily seal the end of a pipe or opening for many different testing applications. Pipe stoppers are mainly used to seal off water, gases and foreign objects in newly laid pipes, or pipework systems that are under repair.
To complement the range of nylon expanding plugs, we offer all sizes of aluminium plugs. These are provided in sizes from 1.5” upwards and are suitable for more arduous duties such as immersion in chemicals and/or higher temperatures.
