Abstract
A test cup for pressure testing tubing comprising an elastomeric sleeve having a belled end, and further including an axially extending tubular portion positioned concentrically within the belled end and defining therewith a fluid-receiving cavity. The tubular portion is mounted to an internal metallic tube which projects axially into the sleeve beyond the reach of the fluid-receiving cavity in concentric relation to the bore through the sleeve. At its end opposite the belled end, the sleeve has embedded therein a plurality of circumferentially spaced reinforcing ring segments of generally L-shaped cross-section.
