A hose assembly of limited conductivity designed to bleed static electric charges such as encountered in paint spraying. The assembly includes, as is conventional, a stem fitting 1, a reinforced hose 3 fitted over the stem 7 of the fitting 1, and a crimped shell 5. The novel element is a conductive coupling ring 13 that is adapted to establish an electrically conductive path between the hose coupling 1 and the conductive element 26 of the hose 3. The conductive coupling ring 13 includes a number of tines 19 and, when assembled between the coupling 1 and the hose 3 will, on its one side, seat against a shoulder 11 of the coupling 1, and the tines 19, on its other side, will penetrate the reinforcement 23 and 24 of the hose 3 and establish electrical contact with the conductive element 26.

Anti-static hose assemblies

A method for mounting one element in surrounding relationship to another element is disclosed in which a groove is provided on the OD of the inner element and a complementary groove is provided on the ID of the outer element so that when the parts are assembled, a channel is defined into which a locking device may be inserted to prevent relative lateral movement between the inner and outer elements.
