Abstract
A coupling assembly includes an annular base which is connected with the first annular friction surface. An annular fluid extensible tube is disposed between the annular base and the first annular friction surface. A fitting is connected with the base and tube to conduct fluid pressure into a chamber in the tube. The fluid pressure extends the tube to press the first friction surface against the second friction surface. The fitting has a main section with a passage through which fluid pressure is conducted into the tube and a flange section which extends radially outward from the main section and is enclosed by material of the tube to retain the fitting in the tube. The main section and flange section of the fitting are integrally formed by a single piece of polymeric material. A plurality of openings are formed in the flange section and are filled with the material of the tube to interconnect the tube and the fitting.
