Inflatable Cylinder Stoppers

Whether you need to carry out air testing, water testing, flow stopping, fluming or over pumping, these expandable cylinder stoppers are an effective and convenient solution. We can supply a range of stoppers, each of which can accommodate a range of pipe diameters.

The Trelleborg Megaplug is a special inflatable plug for pipe diameters larger that 1000mm. Thanks to its unique construction, a large range of pipe diameters can be closed off with a Megaplug, yet it can still be handled and brought into the pipeline through the manhole

Two types of Pronal cylinder stoppers are available; AIRTEST AND 'ORJ'. The Pronal 'airtest' stoppers are available in sizes ranging from 200 - 1000mm. Being specifically designed for airtesting, they are more lightweight than general purpose cylinder stoppers and have the advantage over other airtest stoppers that they can accommodate a range of pipe diameters.
