Patent ID: 8888141

Claim:
A coupling assembly for use with a wire-reinforced elastomeric hose member having reinforcement wire surrounding an elastomeric liner therein, the coupling assembly comprising: a stem defining at least one groove, said at least one groove including first and second walls, a bottom portion and a pair of shoulder portions separated by a width; and a shell at least partially enclosing said stem with a first end engaging the stem and a second end having a shell opening receiving a hose end of the elastomeric hose member, and defining at least one barb, said at least one barb having a barb height, corresponding to one of the at least one grooves and including a tip portion defining first and second edge portions, said tip portion of said at least one barb being sized relative to said shoulder portions of said at least one groove to transfer force developed by deflection of the reinforcement wire to sealingly compress the liner of the hose between said shoulder portions of said at least one groove and said edge portions of said tip portion of said at least one barb corresponding to a swaged state of said shell and stem relative said elastomeric hose member, wherein the at least one barb is not radially aligned with the corresponding at least one grieve when the shell is in a non-swaged state, and the at least one bar is radially aligned with the corresponding at least one groove when the shell is in the swaged state and the shell further defining a seal barb having a seal barb height that is less than the barb height of the at least one barb, the seal barb being disposed proximate the shell opening with the at least one barb disposed between the seal barb and the first end of the shell, and wherein the seal barb lacks a corresponding groove of the stem and sealingly compresses the elastomeric hose member against a nipple portion of the stem when the shell is in the swaged state.
