Abstract
A well swab cup has an annular bushing for supporting a plurality of longitudinally extending wire reinforcing members within an elastomeric cup like body. The reinforcing members are supported in a base cup around the lower portion of the bushing and extend upward to a mid-portion of the body. Approximately one half of the reinforcing wire members extend the full length of the swab cup and the others terminate at a mid-point of the swab cup's length within its elastomeric body.
