Packing tool |
| 摘要 |
<p>A packing tool comprises a sealing element (28) for mounting on a mandrel (18) so as to define a volume (38) between the sealing element and the mandrel; and a ring member (40) for mounting on the mandrel adjacent the sealing element. The ring member is axially movable relative to the sealing element to cause deformation of the sealing element and includes a communicating bore (42) extending between the volume defined between the sealing element and the mandrel and an exterior portion of the tool. <IMAGE></p> |
