  • Patent number: 4394705
    Abstract: A hose assembly of limited conductivity designed to dissipate static electric charges, such as encountered in paint spraying. The hose assembly includes a reinforced hose 1 fitted over the nipple 15 of a stem 13, and a shell 14 holding the hose 1 in compression over the nipple 15 of the stem 13. The novel element is a stripe of conductive polymer 11 in the cover 9 of the hose 1 extending from the static drain 7 to the surface of the hose 1. When the shell 14 is compressed over the hose 1, the conductive stripe 11 is seated and held in secure electrically conducting relationship with the inner diameter of the shell 14.
