Rotationally unrestrained grounding coupling for external grounding of fittings

摘要

A grounding coupling (120) sized for cooperation with a gland nut (122) of a fitting (100) to allow external grounding of such fitting via an external grounding conductor. The grounding coupling (120) is configured for rotationally unrestrained cooperation with the gland nut (122) when the gland nut (122) is in an untightened condition with respect to the body (126) of the fitting. The grounding coupling (120) is further configured for rotationally restrained and electrically conductive cooperation with the gland nut (122) when the gland nut is in a tightened condition with respect to the body of the fitting. <IMAGE>
