Abstract
A swivel adaptor for connection to an inlet pipe leading to a storage tank includes two swivel adaptor members, one of which is rotatably mounted on the other. A plurality of electrically conductive ball bearings are positioned in the channel formed by the swivel adaptor members. The ball bearings facilitate rotation, prevent separation of the swivel adaptor members and provide an electrical interconnection between the swivel adaptor members.
