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.
A coupling assembly component for use in a coupling assembly having an annular base adapted to be connected with a first element and a first annular friction surface which is coaxial with said base and is movable into engagement with a second annular friction surface connected with a second element, said coupling assembly component comprising annular fluid extensible tube means which is extensible under the influence of fluid pressure in a chamber in said tube means to move the first friction surface into engagement with the second friction surface, and fitting means embedded in said tube means for conducting fluid pressure into the chamber in said tube means, said fitting means having a main section with a passage which extends axially through said main section to enable fluid pressure to be conducted through said fitting means into the chamber in said tube means and a flange section which extends radially outward from said main section of said fitting means and is enclosed by material of said tube means to retain said fitting means in said tube means, said main section and said flange section of said fitting means being integrally formed by a single piece of polymeric material.
