  • Rotationally unrestrained grounding coupling for external grounding of fittings
    Patent number: 5929383
    Abstract: A grounding coupling sized for cooperation with a gland nut of a fitting to allow external grounding of such fitting via an external grounding conductor. The grounding coupling is configured for rotationally unrestrained cooperation with the gland nut when the gland nut is in an untightened condition with respect to the body of the fitting. The grounding coupling is further configured for rotationally restrained and electrically conductive cooperation with the gland nut when the gland nut is in a tightened condition with respect to the body of the fitting.
