Abstract:
A method of manufacturing a hydraulic plug. A shell with a circumferential wall, a sealed end, an open end and an axially extending cavity within is provided in which the cavity is defined by an internal surface with an inner diameter which narrows towards the open end. A head of an expander is inserted into the cavity, the expander further comprising a stem extending from the cavity for applying a tensile force (T) to the head. A sleeve is provided on a stem side of the head extending into the cavity, an end of the sleeve adjacent the head having an inner diameter which is less than a maximum outer diameter of the head. The sleeve is formed by expanding the sleeve by forcing the head into the end of the sleeve through urging the sleeve and/or expander towards the other in an axial direction.

Claim (Index 8):
A hydraulic plug comprising:\n a shell comprising a circumferential wall, a sealed end, an open end and an axially extending cavity opening to the open end, the cavity being defined by an internal surface with an inner diameter which narrows towards the open end; an expander having a head retained within the cavity of the shell and a stem joined to the head and extending from the cavity for applying a tensile force (T) to the head, the hydraulic plug being characterised in that a sleeve is provided between the head and the internal surface of the shell, the sleeve overlapping a region of the head to present a combined outer diameter (OD 3 ) which is greater than a minimum inner diameter ID 1  of the cavity where the cavity narrows towards the open end, thereby preventing withdrawal of the head from the cavity.
