Cylindrical & Spherical Inflatable stopper
Cylindrical & Spherical Inflatable stopper 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:
Cylindrical Inflatable stopper.
Spherical Inflatable stopper.
The Standard Range of Cylindrical & Spherical Inflatable stopper are available with sizes ranging from 1 to 96" (25 to 2440 mm).
Cylindrical stopper will not invert (turn over) inside a pipe when under pressure, because they are longer than their diameter.
Spherical Stoppers are used where the position of the stopper is not important and they can be put at any angle and still make a seal.
