Scupper plugs are used to temporarily seal open scuppers to prevent the uncontrolled flow or ingress of liquids. They are used in particular when liquids - such as oil - need to be retained and collected during work on board or in the event of leaks. Thanks to their precisely fitting design, scupper plugs can be inserted quickly and tightly into the openings and removed just as easily. As well as being used on tankers, they can also be used for maintenance work, accidents or for shutting off pipes and drains.
