Abstract
A sealing plug comprises the combination of a stem and sleeve, in which the stem is designed to have an external taper such that, on installation of the plug by a setting tool, sleeve material flows into a gap between the sleeve and taper to assist with locking the sleeve and stem together. Furthermore, the tool nose piece has a conical taper designed to cause sleeve material to flow, initially on installation, radially outward to effect locking of the plug into a blind hole into which it is being installed.
