Claim Text:
1. A device, into which a support core is to be inserted by a field expansion apparatus, the field expansion apparatus having a pressure applying means defining a radially expandable inner surface and a flat surface radially outwardly extending from the radially expandable inner surface, the device comprising: an elastomeric tubing, having a forward end opposite a rearward end and an axial bore extending therethrough configured to receive the support core; and an adapter, having a step portion defined by a radial outer surface and a flat surface radially outwardly extending from the radial outer surface, and an axial bore extending therethrough, the axial bore having a diameter substantially the same as the diameter of the axial bore of the elastomeric tubing; the adapter being positioned substantially coaxially with the elastomeric tubing between the pressure applying means and the elastomeric tubing such that, in response to inserting the support core from the rearward end into the elastomeric tubing, the flat surface of the adapter is pushed against the flat surface of the pressure applying means by the elastomeric tubing, the interface between a rearward end of the adapter and the forward end of the elastomeric tubing is of high friction so that the adapter and the elastomeric tubing expand radially in unison, and the radial outer surface of the adapter exerts a radially outward pressure against the radially expandable inner surface of the pressure applying means.
