ABSTRACT:
A test head for enclosing pipe ends to test any diameter pipe within a plurality of pipe diameters in a preselected range which test head has a seal ring assembly which has a resilient body with a counterbore of a larger volume than non-resilient segments in the counterbore and mounted on the body to provide a volumetric space or gap between the segments and resilient body to enable the resilient body to initially move in response to fluid pressure toward sealing relation with the pipe without engaging the non-resilient segments.
