The versatile Pipestoppers® Inflatable Stoppers can be inserted and retracted through small holes and then inflated to full size for stopping operations. They are used to service a wide variety of industrial applications and are available in the following ranges:

Standard Inflatable Stoppers:

Cylindrical Inflatable Stoppers

The Standard Range of Inflatable Pipe Stoppers are available for immediate delivery with sizes ranging from 1 to 96″ (25 to 2440 mm).

Cylindrical Inflatable Stoppers will not invert (turn over) inside a pipe when under pressure, because they are longer than their diameter.

PetroChem Inflatable Stoppers

Heat Resistant Inflatable Stoppers

The PetroChem Inflatable Stoppers are identical in appearance and performance to the Standard Inflatable Stoppers, except that the inside inflatable latex part is enclosed in a thin, flexible rubber that is resistant to the petrochemical fluids and vapours.
