ABSTRACT:
An apparatus for seating a ring gasket 100 in a groove 41 in the end socket of a pipe or coupling includes a plurality of radially oriented prong hooks 7 spaced at regular intervals around a circle, and cooperable with an equal plurality of interposed, upstanding studs 24 extending between a circular lower disk 22 and a sectored upper disk 23 defining radial slots 27 to accomodate the prongs. The prongs are driven inwardly together on a support 1 capable of translational motion along an axis X-X perpendicular to the plane of the prongs, and reduce the diameter of a gripped gasket by deforming it into an undulating polygonal configuration. The gasket may then be inserted into the pipe end, whereafter the prongs are disengaged and the gasket expands elastically to seat in its pipe groove 41.
