Abstract
A stress-bearing umbilicus for conveying fluid between a stationary body and a rotating body comprises an umbilicus body made from an extruded first polyester elastomer material having flexibility. A support block, made from a second polyester elastomer material, is over-molded about at least one region of the umbilicus body. The second polyester elastomer material has flexibility that is greater than the flexibility of the first polyester elastomer material. Surface energy of the region between the support block and the umbilicus body is increased before over-molding to prevent delamination and peeling.
